Hi - I have a HeaterMeter v4.3.4 (and RPi 3b) that I soldered up a few months ago. I've done 3 cooks to great success. But today the heatermeter will not cooperate.
I booted it this morning to come up with either blocks in the LCD display, nothing in the display or random characters with each power cycle and otherwise unreponsive buttons.
Not trusting my soldering skills I opened it up and reflowed a number of connections (I removed the ATMEGA when doing the socket connections) and voila it started to work. Put back into case, still worked. I moved it out to the Weber and it didn't work anymore. Repeat 2 more times. On the last go around it appeared to work fine, LCD, fan and wifi were all working like normal. But after 30-45 minutes or so it become unresponsive (last pit temperature was displayed on the LCD but the web interface showed just dashes for pit temp).
I was reading the thread "Why can't this thing just work... (frustrated)" and in there are some debugging techniques that I will try but I thought I might ask for some areas to focus on in the meantime.
Other data points
- it also doesn't work without the RPi attached so I don't think the Pi is the problem (guessing though)
- I ensured the LCD pins were NOT touching the USB connectors of the Pi when fully assembled
- in the last instance that it was working (for a while) the pit probe config had been changed (corrupted) away from the previous setting (ie it wasn't set to a thermoworks probe but something else ... I reconfigured it back to and all was fine). Does this suggest something with the ATMEGA connections possibly? Or just the result of numerous power cycles?
Anyhow, any ideas are most appreciated.
(Brisket is patiently waiting in the fridge.)
Many thanks in advance.
