not sure, what you mean with “intergrating in OH” and “must save last operating status”.
Correct me, if I’m wrong, but this sounds like a perfect “dumb appliance - smart plug” answer? My bet is, there’s a whole bunch of heaters which don’t rely on a “dead man’s switch” to run (which of course is risky - but yeah…).
So, you do seek for some recommendations on heaters which can be driven by a wireless plug (zwave e.g.)?
I am asking for a heater (manufacturer and model no.) that meets my requirements and ideally is already being used successfully by someone.
Yes, a “dumb appliance - smart plug” scenario would be the simplest solution, but unfortunately the dumbness of the heaters can’t be easily gleaned from the product specs, and I’d hate to order heaters and then have to return them because they’re too smart (and keep the user from burning the house down ).
