Wall socket to device that can - Off-topic

Hi all,
I need a device that plugs into your wall and can connect to by an app on your phone to turn on. Or similar.
So my aim is to be able to turn a specific wall socket or plug on with my phone through an app or something. Also turn it off. I want to plug a lamp that has a USB connection(only way of turning on the lamp).
Kind of like the tesla cars and their app able to turn the heating on etc etc. Or those house thermostats you can control with your phone.
I'm sure there's a smart plug or something? Anyone know?
Thank you

Well I ended up getting this, it's on the way. Hopefully it's sufficient.

Galaxy S dead?

Hey everyone,
My galaxy S ran out of battery, I plugged it into my car charger and it went into download mode? Got home, it completely died. Plugged it into my charger and the screen wont even turn on.
Can someone help?
Anyone? Ideas? It's completely dead.
Tried removing the battery, wait for say, 2 minutes, and putting it back on?

Yeah, I've tried this. Won't work.
This may sound stupid, but could it be that the charger / wall socket is the one broken? Try plugging it into a computer's powered USB socket.
If you're on a laptop, this is usually all ports except one that doubles as an e-sata port, and for desktops, this means all ports. You might need to plug the laptop into a wall socket though. Don't connect it to a USB hub.

Tried 3 different computers :/
1 of 2 things
1- your battery is ****ed. and i think thats the case because u plugged it in a car charger
" why you people keep doing that "
2- your phone is fried " over power from the charger "
again
" why on earth you people keep charging from the car. even the official chargers are stupid . any your car might not have stable elctric current in it. #$#@ >_<
try different battery.
Did you connect your phone before starting the car?
Some chargers don't have a fuse, or the fuse is set for higher currents.
Some cars will run a peak-current (a high jolt of electricity) through the electrical systems when you start them, this might have fried your battery indeed.
Thanks for everyone's help. The car chargers fuse is blown. The battery isn't dead though, just went to a Samsung service center and he "shocked" the battery into starting. Phone went back into download mode so he is keeping it for more diagnostics.
No phone for about a week . The annoying this is, if this was an iPhone they'd replace it on the spot. I love Android, and I couldn't live without it's features, but Samsung really make it hard to love their warranty process.
Just an update for anyone with future problems similar to mine.
The memory had died, and Samsung replaced all the internals of my Galaxy S.
Also, one more thing. Since getting my phone back pressing the power button turns the screen off but doesn't lock my phone. When I press a button to wake my phone up it goes straight into whatever I was doing before, no lock screen.
How do I fix this?

I had that same issue when I swapped from an 8 GB UK to a 16 GB Australian model. I don't know the cause but it's just a bug, if you reboot it should go away. You can also try something like adding a screen unlock pattern. I still get the issue every now and again but I just fiddle around until it goes away.

[Q] Battery discharging when on powered USB

Here's an interesting discovery - would be interested to know if anyone else has the same issue.
Basically, my old WM6.5 phone (Touch Pro) used to take charge from a powered USB socket, even when the computer was turned off.
Plugging the HD7 into the same USB socket, and the phone won't charge. That's fine, I can understand there may be valid reasons for it.
What's *really* interesting is that if I leave the phone plugged into this powered down PC overnight, the battery is pretty much dead in the morning. Compare this to leaving the phone unplugged completely, and I'd generally see 15% battery usage overnight.
The solution is pretty simple - don't leave the phone plugged into this USB socket, but it seems odd.
Any chance someone else can try this?
Is the Zune client on your pc open because my phone will not charge with zune open
but once i exit out of zune on the pc it charges fine...
ive lost my charger and too lazy and cheap to buy a new one so im just using the pc to do it....
no - the PC is actually powered down. However, with soft power switches, the USB port stilll can get power, as proven by my ability to charge my Touch Pro from USB when the PC's off.
I'm not sure what could be causing this, but i will try to see if mine is the same too, then i will post feedback
I've charged mine on a USB port at work, but there isn't any Zune software in the way there... Honestly, I don't sync through USB, so I never noticed this, but at work I have used the USB port on our camera system to charge my phone...
most likely cause is the fact that the computer reduces the amount of current send to the usb port when powered down.
normaly all that is needed is a move of the mouse or a key press to power the computer back on.
now both the keyboard and mouse are low power devices.
now my guess is that the touch pro needs less power in standby then the hd7, and therefore the first will charge and the second will drain.
so to solve this question you need to measure the power comming from the computer in standby (powered on it's 500mA), and both the phones in standby mode.

Here's what I find odd:
The phone will not charge unless powered on. For example, if I have the phone turned off, and plug it into the wall charger it came with, the phone boots up. It will NOT charge while turned off.
Anyone else notice this?

i saw someone mention that the led won't turn on during charging while the phone is turned off.
sadly he didn't wait long enough to see if the led turns on when the battery is fully charged.
also i have no idea which model he was using.

I posted earlier about charging issues on the HD7: http://forum.xda-developers.com/showthread.php?t=849548
What I found was that if you have the HD7 plugged into the USB port and then you suspend/shut down the PC, it'll stop charging (while all other phones I've used - iPhones, HD2, etc. - will keep charging).
Once you suspend/shut down, you need to then unplug and replug the HD7, and it should start charging again. Not sure why this happens, but I need to do it every night, otherwise I have a dead phone in the morning.

That is apparently a "feature" of WP7-- the phone will automatically turn on when plugged in.

[Q] Modify car cradle to automatically enable car mode ?

Hi there,
I just bought an active car cradle for the Htc HD2 (Carcomm), no problem, working as expected.
Then I began wondering why the phone would not go into car mode when connected to the car cradle... If it's a car cradle, it should put the phone into car mode, right ??
So I was wondering what could possibly trigger the phone into car mode when connected to a charger.
Found this in another thread (http://forum.xda-developers.com/showthread.php?t=767961):
To the person who wanted to know about connecting pins 2&3 to 4 to create a car doc? Looking at the USB spec datasheet It's not that simple. You need to insert a voltage divider across the data lines and tie it back into the 3.2v of the device. A little more trouble than it's worth unless you are doing it for the learning experience.

and also from user dabigcheezze :
unfortunately it is a problem with froyo, whenever the phone is placed into dock mode, no matter what the charging input, it will only show up charging in usb mode, i have a homemade dock cable with pin 4 to ground, when i hook that up to my 1 amp charger it only shows usb, using a normal cable it shows ac charging, it has nothing to do with the HTC dock, it will happen whenever the phone is placed into dock mode, it also locks the vol output on the 3.5 jack 3/4 up....sooooo stupid.

Does anyone know about grounding pin 4 to enable car mode ? what about power, is the charger powering enough the phone while using BT, GPS and navigation ? Also, the limitations in Froyo are they gone in Gingerbread or could it be fixed ?
Thank you for sharing your experience, I would really like to have a car cradle working 100%
Nobody ?

Willing to share ?
Hi !
Just wait I can contact the guy I wish to buy that second hand HD2 first, then find an appropriate car charger craddle, and I'll look for a solution.
Don't know how to automatically enable car mode, but just solder the 2 middle wires in your USB cable together and you'll get 1A instead of 500mA, which charges way faster. Your car charger needs an output of 1A, of course, else it's just gonna remain 500mA.

Thanks for your reply. Yes, it's true. I've seen this small hack to enable AC charging for cheap chargers that are charging with USB mode (400mA I think).
My charger was good enough to provide AC charging (1A), which is great, but not enough to enable the car mode...
What I would like to confirm is if grounding pin 4 will really put the phone in car mode when plugged into the car cradle, before doing it myself...
Do not hack the hardware!
Use a software
http://forum.xda-developers.com/showthread.php?p=8178010
Thank you for your response.
But... is it a software for windows only ?
I run Android on my HD2
Unfortunately, the software only runs on Windows Mobile :-(
So you have to try that:

I personally ordered the original car holder from htc and it is really a very good one!
Excellent !!
I think that if the mentionned modification works with a HD2 AND a Desire HD, the official Htc android software should work also, like the windows software in the video.
Thank you, it's great ! I will post here my results when done
Even easier - try using PhoneWeaver (can't add a link as a noob)
It's basically an app for setting your phone's parameters, based on all sorts of external influences, such as time, date, power source etc.
So, for example, I have the following settings:-
6:15 am - turn phone on, set volume to Normal
8:15am - set volume to low (for when I'm in the office - its a personal mobile)
4:45pm - set volume to Normal
6:45pm, turn wireless on (as I'm at home, and browsing is much faster)
10:00pm - turn phone / wireless off, set volume to low, start SPB Time (my alarm clock)
Additionally, I have the following:-
If external power is detected AND Activesync isn't running (ie it's not connected to a PC) then turn on Bluetooth and increase volume (this is because the only other possibility for this environment is when its in the powered car cradle)
If external power is detected AND Activesync IS running, turn Bluetooth off, but turn wireless on
It's completely brilliant - never fails and I never have to remember to do anything

[Q] Charging issue connected to car stereo USB

Hey all.
I plugged my phone into my friends car stereo usb yesterday to charge it, and it kept connecting/disconnecting rapidly, going from charging to charging about twice in a second repeatedly. The only way I could get it to charge is if I shut the phone off.
Any ideas of why this would be?

Insufficient current output from the stereo's USB socket would be the obvious guess.
Is this going to be an issue with all car stereos made before the HTC One though?
It wasn't JUST the charging that would start and stop rapidly. The USB Connection and Debug Mode would connect and disconnect at the same time, like the connection was actually being turned on and off.

I have this same problem with my girlfriends HTC One. When I plug it to charge from the car's dedicated USB port for charging it just connects/disconnects over and over.
Never had this problem with the Note 2 or my Nexus 4 and 5. They charged no problem.

Tasker In-Car power issue

I have built a Nexus 7 into my car and I have a small issue.
I need a tasker profile:
When I turn the car on, the screen turns on and music plays.
When i turn the car off, the music stops and the screen turns off. (along with other stuff)
I have created a "test" version of all this so when I connect a power cable (i.e when charging) it turns the screen on and plays music.
When I disconnect the USB (i.e. stops charging) the screen goes off, music stops, bluetooth off etc and all this works fine.
However, the USB will always be connected with power coming through so I cannot use this option. I need another way to detect if the car is on and when it turns off so I can run the correct tasks.
One option i thought of is buy a wireless charger and build it into the car. When my phone is placed on the charger, send a text message to the tablet to turn it on, and when i turn the car off the charging will stop, then the phone will send a text to the tablet to turn the screen off etc.
However after purchasing the wireless charger, i realised everytime i get a call or take my phone of the charger for whatever reason, the screen will go off and music will stop, so this isnt an option either.
So the question is, what can i do so tasker can detect that the car is on or off so the nexus can perform the tasks?
Hope that makes sense

You do realize that you really have two problems, right? The Nexus 7 will not know when the car is started, or stopped. Unless you can disconnect the power, manually etc.. If you can do that, you can send a command in fastboot to force the N7 to power up when power is connected, otherwise you'd have to boot it up manually.
You could unplug the USB charger.. Or have the tablet turn off after N hours of inactivity, although how do you detect "new" activity if there's no change when the car is started.
If your car has bluetooth, you could detect that as the "turn off" task perhaps, but turning on is probably your bigger issue.
Will the wireless charger idea work?

No idea what you mean by wireless charger (2012 model has no wireless charging), or how you'd control it with the phone. And unless your tablet is a 3g one, I don't know how you'd directly communicate with it either.
I just put my phone back to stock so I had to uninstall Tasker, however your tablet does not pull power once the car is off correct? I had a power based one as well, I remember testing it with a surge protector. I could leave the USB connected but flip the surge protector on and off (to mimic power to the phone being halted). To my knowledge when the car is off your USB shouldn't be drawing power therefore you could run the profile off that. Export the profile and post here. I'd like to help test it.

My last four cars (current and previous of wife and my cars) the lighter plug stays powered when the engine is off.
I think it's getting increasingly common for the plugs to stay powered. So there's no way for the tablet to know the car is off unless the car has bluetooth and you can look for that.

I have actually found the exact opposite to me true. My wife's 2014 Pilot goes off as well as my 2012 Veloster whereas my 2001 Sable and her 2007 Passat left them on. I'm not sure if you can resolve your issue then. I'll keep looking into it. You could trigger it based on speed I think

I suppose that could work.. Find out the speed for several periods in a row, if it's zero, assume it's time to shut down. But that'd mean it's playing music etc during that period etc.
IMO bluetooth, or a plug he can turn off, is really the only way if his USB is powered up all of the time.
Also remember, he has no way to know when to power UP either. I still maintain that's the bigger problem, especially if it's a fixed install and he can't poke the power button
At the moment, its connected so when the car turns on, the USB is powered up and when the car turns off, the power in the USB stops. So at the moment, my tasker profile works on "when charging" do Task A, when not charging do Task B. And it all works fine at the moment.
However I am having issues with charging, (The device is not charging fast enough when turned on and the battery drains over a couple of days) so i planned to keep it always charging, so the power in the USB will always be there regardless of if the car is on or off. So i cant use the "when charging" on tasker anymore. So i needed a new way to it to figure out when i got in the car.
Here are my ideas:
1. Have a wireless charger in my car for my phone. (Not the tablet). When i get in the car, i could put my phone on the charger, have the phone send a text to the tablet to turn it on. When i remove the phone from the charger, send a text to the tablet to turn it off. Simples
2. Connect a wifi router in the boot or something and have it start up only when the car starts, and turn off with the car. It doesn't have to be connected to the internet, it just needs to power up. Then i can do a 'When wifi near' on tasker to see if the car is off or on, and turn the screen off accordingly.
3. Connect the tablet to my phones bluetooth. Whenever i get in the car, they will connect and the tablet will power on. when i leave the car, it will power off. (Not the best option since it will stay on even if i am near the car)
4. Similar to option 1, but have a nfc sticker in the car. when i swipe my phone on it, it communicates with the tablet and turns it on, n then off when required. but i dont want to do this since i know i am going to forget to turn it off one day.
I don't really want to do the speed option, since i want it to turn on as soon as i enter the car, not when i start driving, and i want to be able to park up and use it when i need to put an addess in the sat nav etc.

If your charger isn't charging fast enough, you're using a crappy charger or one that isn't designed for Android. If your car has a built-in USB port, those are usually super slow, maybe 500mA, most less.
Anyway, glad to hear that your power follows the car state, that makes it all simple.

I've tried about 20 different chargers, up to 2.5amps. The problem isnt the charger. The problem is i dont drive the car long enough to give it time to charge. So if i drive the car for about half an hour a day, for the other 23.5 hours, its on standby. so the battery is always going to go less. So thats why I plan to connect the charger directly to the battery so it will always be charging.

Oh, I thought you had the tablet turning off when the car went off. If I were you, I'd set up a profile that turns off the tablet if it hasn't had power in a few hours, pretty simple to do. On Power, set a time var, every so often check that time var to see if it exceeds your threshold, and power down if so.
If you don't have much installed, it should be a fairly quick power-up, especially the plug goes hot when you start the car.
BTW I hope you're considering cold and heat if you're leaving the tablet in the car. Leaving it in the heat all summer will will the battery.
You can use Timur's kernel, it senses power to turn N7 on or deep sleep it.
Also charges N7 while using OTG.
It;s designed for car install.

I agree, you need to get at least a 2A charger for your car. My wife would watch Netflix on long drives and my car USB port or the normal USB charger I got for the cigarette lighter worked until I up'd it to a 2A charger. I can have screen on for hours while streaming video and still fully charge the tablet in a reasonable amount of time.
