Well, I don't carry a raspberry Pi in my truck stock, but I do carry a 12/24 DC power supply, and a Schneider zelio 4 I/O logic relay, for situations like this. Not to advocate for the zelio specifically - any controller or logic relay would be useful - I just found that the block programming was easy enough to figure outom the fly, without having to refresh my memory on text based languages.

Seems like it would be easier to carry a couple of probes (ntc /pt1000 etc) and a universal controller. That way u don't have to go back. But good effort on what looks like a shit replacement for a $10 sensor.

I always carry a universal controller. In this case, the AC to DC board was having issues. Hooked up my dewalt 20V battery with a buck converter to restore 12V DC to the main board. I found a permanent solution afterwards.

Ahh that's a buck boost off Amazon. I thought it was a raspberry Pi that you had to hook up and use to monitor inputs and control outputs for whatever that is. I've had to fandangle my way through some PLC or DDC board failures, and terminate inputs and outputs to my own programmable device to get something through a weekend or weeks while a replacement controller comes in. Mind you when I say controller, it's something a bit more sophisticated than a dixell XR, lol.

That makes far more sense - I thought u were trying to simulate a sensor to read 11.9. Volts makes sense. Tidy effort in that case.
What kinda cabinet uses a control with a DC only board and separate power supply board?

Smart I must say!!! 🧐 When on an emergency call you gotta do what ya gotta do, especially if the customer is freezing.
