- Thu May 16, 2019 7:26 am #82322 Hi, I've made weather station using Wemos R1 D1 and few sensors, everything was working fine for almost half year untill last weekend when it stopped sending data to ThingSpeak. I've trying to restet board but it didn't help, finally I checked what board is printing in serila monitor and I saw this:

Decoded stack:

I was trying to fix this issue and find any solution in many forums but unfortunately board prints same message I think the issue is somewhere in code.

Maybe your board is just dying: have you tried the same sketch on a new (or other) board yet?

Assumption is the mother of all f*ckups. At least: that's what I'm assuming.

Yes, I was trying to run same sketch on two other boards and it wasn't working. I've even tried to make new account and channel on ThingSpeak but it didn't help. It is interesting when I check in router, board appears as connected.

- Fri May 17, 2019 1:38 am #82342 the location in core_esp8266_main.cpp is roughly where loop() gets executed, so probably your loop() gets stuck. Try disabling all sensors and send dummy values, then start re-adding one sensor after another ...
