hello
my problem which i hope is an easy fix is as follows,
I have 4 temp sensors for different rooms in my house and i’m wanting them to switch on my gas boiler (heating) when the temp drops below a set temp on any of the zones. (over heating room restriction via standard trv)
i am currently doing this with generic thermostat controlling a sonoff relay (device)(which calls for heat) which works, but it seems from monitoring that if say 3 zones where all calling for heat when 1 zone reaches its desired temp it sends a turn off boiler sonoff command. which it does leaving the rest of the house cold until another zone drops below temp sending and on command.
in conclusion i would like the boiler to call for heat if any of the 4 zones are below at target temp. and switch off when all zones are at temp.
many thank
