Yes, it should, as long as another rule is not over riding it. Perhaps this is a bug with the new rules code?

The last clarification. Should the change in the output be instant or only after a restart?

[image] Daemon_D: Should the change in the output be instant or only after a restart? I would expect it to be instant. Since the last code change with the new relay rules in it, I think when the rules are saved, all the rules are reset but the default relay logic isn’t applied correctly.

[image] Daemon256: Now I will describe how it actually works (Firmware HysteresisRules, All rules X): Relay default - OFF → On the corresponding output, logic 1 Relay default - ON → On the corresponding output, logic 0 Okay, my relay board is happy with the outputs of the PCF chip - it must…

I am using standard aliexpress relays or relay via conventional power transistor. They all wait at the input for ON 1 and OFF 0

Right, sounds like we need a simple INVERT option on the configuration screen. Can you raise a feature request on GitHub?

Is there a guide/video/document that explains all the parameters that can be set inside the Webinterface and how one can set those parameters correct considering what kind of battery one has ? I am trying to learn how the diyBMS works so i am testing with a bench power supply to simulate the batter…

@stuart or anyone that can help, The recommended thermistor on the GitHub page is a NTC 10 kohm 3950k, B57891M Series. I have a bunch of NTC 10K 3950 thermistors. MF58 series. The specs on the data sheet are fairly close to the one that you had listed. I’m assuming I should be okay using them. J…
