Hi, did a search in the internet but didn’t find anything even near the price of a Sonoff.
so I’m going to give these a try https://www.amazon.de/gp/product/B00616X860/ref=ask_ql_qh_dp_hza
30sec open/close time.
How are people getting on with the sonoff as a thermostat setup ?
I have decided to go for the Bruh Multisensor so that the thermostat is away from the heat source and so far i am quite impressed with it.
Do some actuators take longer than 30 seconds then
Turning on and off radiators will always produce temperature oscillation in a room, both because of the on/off action itself, overshoot and also the time that the sensor takes to register the heat increase. The larger the thermal mass of the radiator the more pronounced the swings will likely be.
A much better approach is to reduce the flow in the radiator to a point at which it’s temperature becomes stable providing just enough heat to maintain the room set point. e.g 33% on. This assumes the flow temperature remains fairly constant of course.
yep the thermal actuators I tested took at least 2-5 minutes to either open or close.
