I believe I had the same issue last week with a couple controllers that had been unplugged for a while. After restarting the pi all devices showed back up.

Funny, been running nodemcu for years on probably every firmware and never had that happen. Switch to mini, new problems everywhere

Loaded whatever the latest in the fermentrack listed firmware was. 11, 12 maybe

I switched the temp sensors to 5v and everything seemed solid for 40 min, then both readings dropped out again. I have another new ps hooked up now, will see how it goes. When everything booted back up, both temp readings were around 212f then started creeping down slowly. I have not seen this...

This is more in line with the pcb I'm using

Have an older board. So one can't just disconnect the 3.3v out wire and jump 5v to the sensor's feed?

The diagram you posted last week doesn't show a pull up on the 5v circuit. Should it be or is the current on the 3.3v ok?

Interesting, has a new 2a power supply. The temp sensors are on 3.3v at the moment, could this effect my problem? Would like to run on 5v anyway (my board is setup for 3.3v). Can just supply the sensors with 5v or do I need a resister?

So after a completely fresh build (let every bit of smoke out...), I'm having a problem with my temp sensors dropping out after 5 min or so. Anyone have any suggestions? Have checked wiring

This seems pretty solid so far. Relay switches on and off promptly.

It appears Thorrak has the correct diagram for this relay. Dc+ directly feeds low jumper and dc- feeds the high jumper pin, the com pin also goes through a 1k resistor to the opto

So your saying if I remove the jumper and jump 5v supply to the high pin it should switch properly? With the jumper removed, I already have 5v on the high pin?

Would this be as simple as jumping d5 to the lv side and the hv pin out to the relay? Or is more hardware needed?

Do you remember on you older pcbs w/shifter do they use all the channels?

Pos, neg, in1. Does have an optocoupler.
