Hi there!
I keep on getting this message when running a self test:
Any idea of how to proceed?
Thank you!
it looks like your heater PCB isn’t receiving any power (a DC voltage is being applied, but there’s no increase in temperature). Were any modifications made to it (software or hardware)? Try reconnecting the wires from the HAT to the heater PCB?
Ummm… It could be that I just replaced the heating extension HAT? Is the problem on the PCB or could be that HAT issue?
Thanks! 
Hm, and you installed the associated plugin?
Hm, I wonder if I ever tested self-test + the temp HAT. If you start the thermostat, are you seeing anything unexpected?
Hi Cameron 
Doenst say anything but then it doesn’t raise the temperature…
The pluggin is installed
hm, I’m not too sure. Just some ideas:
- Does it work again if your remove the HAT?
- Any visible damage to the heater PCB or cable?
Hi! I’ve been running some tests. I changed the PCB and also tried with another HAT, but the error still persists…
I have a cluster of 8 Pios — only four of them have the plugin installed, although in the general config.ini file it’s set up like this:
[temperature_automation.thermostat]
Kp=0.017
Ki=0.0
Kd=4.0
In the individual config sections for each Pioreactor, there’s nothing written. Only one of them is giving me problems… I’m not sure what else it could be.
Have a good day!
So if only 4 of the Pioreactors have the plugin installed, move the
[temperature_automation.thermostat]
Kp=0.017
Ki=0.0
Kd=4.0
to the specific worker config.inis that have plugin installed, and change the config.ini’s section back to:
[temperature_automation.thermostat]
Kp=2.6
Ki=0.0
Kd=4.6
Have you swapped heater PCBs? The problem might be coming from there.
SOLVED! Thanks
Awesome
