I am working on an ESP32 project. I am replacing Truma’s ultraheat control and replacing it with an ESP 32 and an SSM1306 Display. I’m happy to share blueprints/hardware if anyone else is interested.
I would need help with 2 things. I dont think it’s that hard, but i’m stuck.
( relay 1-3 is pulled by differences in temperature.)
First:
(conditions below Dallas)
I would like the conditions for 1000w to only run if also GPIO16 (id= activate1kw) is true.
The condition for 2000W only if also the condition for 2000W GPIO23 (id= activate2kw) and GPIO16 (id= activate1kw) is true
next thing:
(Binary sensor)
If GPIO 25 id= turnoff is false, i wont all three relays to turn off, and i want them off untill GPIO25 is true
Plz help me
