I'm having trouble getting the temperature relay logic to work. I have a ruuvi, visible in cerbo, showing 21C right now. I'm trying to set this to trigger if the temp drops below 21C to turn on a heater. However, I cannot get that logic to work. I will want it to ultimately be, turn on relay at 2C and turn of relay at 10C. I'm using 21C now because it's room temp and it's easy to warm it up or cool it down to trigger.
For example, right now at 21C but with activation at 24C and deactivation at 39C, it's 'active'.
Activate at 25C, deactivate at 0C. this active
20 and 0, still active, 1C and 0C, still active. 1C and 1C, deactivated.
Activate at 0C deactivate at 30C, inactive. ??
Any help on this appreciated,.
