Hm, I have an issue my the Solar node. It heats up too much in the sun. The panel getting hot might be one thing but the inside of the box where the batteries are? That worries me.

I installed a BME280 so it sits inside the box and the temperature reading is actually quite helpful here. I pulled the plug when it got to 55C within hours.

Has anybody experienced that? Isn’t that a problem for the batteries? I don’t need this exploding!!
