The code looks like it uploads and fails to make noise or light up the led strip. and the serial output is a garbled mess (I tried different baud rates with no success). I have also check my wiring with a multi meter and scoured any wiring schematics.

I do want to stimulating the temperature. Also interesting theory, it would be cool to put it to the test. But I need some way to simulate a thermistor. Also, The testing rig I want to build could be a cool demonstration piece for how a thermostat works. I might donate it to some tech school when I’m done with it. Time will tell

It would be fun to torch a google device while laughing psychotically.

Yeah I want to simulate the temperature readings. No blow torches or extreme heat preferred.

Dam, my old antenna was powered over the coax. That’s probly what did it.

Cool, Thank you.

Thanks. Btw i found a DC auto transfer switch on amazon. https://a.co/d/a6pnd9B I assume i wire the car power to the “DC power source” so when it disappears it switches to “battery power” aka solar power. And the load terminal is wired to the DC in port on my bluetti

Good thing i asked the experts. Any i deas for a way to switch to solar power when i turn off the car? Like some form of diy relay switch

True.

Its running off a 5v usb brick. I am trying to alluminate the way to the bathroom for my mom late at night so she won’t trip or kick the household black cat. Also I ordered some PIR motion sensors to turn on the LED strip.

Its a product Safety standard. Here is a Wikipedia page. https://en.m.wikipedia.org/wiki/UL_(safety_organization)
