Controlling temperature

[jlauzon9]

Good day,

Amazing software, thank you for developing it. I am in the process of building and programming (via TerrariumPI) a bioactive enclosure. I live in a bit of a cold city and want some supplemental heat for cold winters or when my partner blasts the AC too much at night.

I'm struggling to figure out how I can control a ceramic heat emitter with a BME280 temperature probe. It seems all the relay control I get in the area setup page is based on timers. Based on the text from the Setup guide:

"The system uses the sensors alarm values to determine the right conditions you want. For example, using an area with a heater relay and temperature sensors will try to get the temperature in the middle of the minimum and maximum sensor values. Either by using a dimmer or by just toggling on and off. By changing the sensor alarm values, you can raise or lower the wanted temperature. This is the basic logic we use."

...am I right in assuming if I want to maintain, lets say... 25c I should set my low alarm at 20 on the BME280, and the high alarm at 30? And apply a -2offset for nighttime if I want it to be 23C? And in addition, I would not need to set a power on or settle time value?

I would set the relay for this heat emitter in the low alarm tab, but not do anything else?

Thanks to anyone who can confirm or correct me.

Hi, I guess you did not use the area type heating? Because that should give you a sensor mode.

You are right with the 20 and 30C degrees. The settle time and power on fields needs to be entered 0. And then it should work like you wanted.

Any updates on this?

Got it set up. How long after it reaches temperature should the software shut the relay for the heater off?

I was set at 20-24 low/high alarm, and the ceramic heat emitter was still on with the temp around 23-24 degrees Celsius. I am using a Kasa Smart Dimmer Outlet (but i don't think it is recognized as a Dimmer with TerrariumPi.
