wall mounting touch screen and Pi

Hi there, I'd like to wall mount my Pi so it can control the heating. Looking for wall mounting cases I did not found much and the obvious choice seems to be the official Pi case. However, I am concerned as that case hosts the Pi at the bottom (or top if you want) and there is no bezel where the Pi ...

Re: GPI triggered as soon as cables are in

Hi David,

Capacitors have been in for a few days and the Pi has not shutdown anymore - thank you!

What happens from an electronic point of view? Why isn't pulling up the GPI enough and extra capacitors are required?

Re: LIRC: mode2 continuously receiving pulses from TSOP85

Thanks,

I can shield the IR sensor but I am not sure it would work as I still see a stream of numbers with all the lights off and the Pi covered by a dark surface?

Hi I'm digging this thread out as I have the same problem. The difference is that if I aim the desk fluorencent light to the IR receives, the stream of garbage stops (well, not completely) and if I point a remote at it and press a button, I can see something happening on screen, but every time I pre...

Re: GPI triggered as soon as cables are in

The Pi switched off again and the logs confirmed the shutdown routine had been initiated. I then found the culprit! It's the thermostat which sits by the Pi. It's on/off and mechanical type. Boiler line is, surprisingly, 240V. I turned the dial back and forth a few times to engage/disengage the boil...

Re: GPI triggered as soon as cables are in

Thanks again. This morning I found the Pi switched off. I don't think there was a power cut as my oven's clock would have reset. Do you know where I can check some logs to try and find out if the shutdown routine was initiated? Thanks! Edit: no apparently. I have added logging into the file myself. ...

Re: GPI triggered as soon as cables are in

HI there,

Thank you, it worked! As the Pi has internal pull-up resistors, how come that did not work with 5cm of wire connected to the GPIO?

Thank you again!

Thank you for taking the time to test this, appreciated! Yes, the relay board is powered from the Pi. However, it's been in operation for months and I never had any issues. I have to say I did not check WHAT causes the shutdown but I assume it is the shutdown routine as it does not happen if the but...

Re: GPI triggered as soon as cables are in

Hi,
No. As a test I plugged the button in while it was on - and the shutdown routine immediately started - but if I leave the button plugged in the Pi boots and immediately shuts down, via shutdown command.

Re: simple temperature monitor and relay activation GUI

Anybody? I found ethernet controlled relay boards but not ethernet sensors.
I guess I could just pack another Pi with it. I don't mind, it's having 3-4 Pi's scattered around the home does not really makes me enthusiastic.

ideally, as a final goal, I'd like having something like that. But I am not a developer and it may be too much to aim for.
