I have a Cerbo GX with a top and bottom Ruuvi tag in my freezer box.
The freezer box has about 6-8 deg temp difference between top and bottom and
I have a mixing fan which runs off the relay when the temp is below a set
value and this works.
What would be even better would be the option to run the relay when both:
1. Temp for both tags is below setpoint; and
2. Temp difference between both tags is greater than param;
I guess its possible in node red but I have'nt tried to load that yet.
