This might sound a little daft, so apologies in advance. Have an MVHR system at home and it’s controlled from a wall panel unit (see subject).
Something that’s annoying is that, occasionally the MVHR can suck in smoke from the outside air, stinking the house up a bit. What I was hoping to try out is, if there was some way of controlling the panel remotely, i.e., turn it off / on using OpenHab or some app.
No idea if this is even possible to be honest so apologies again
If the remote display is hard wired you could add an additional contact for on/off and use something like Esp8266 with mqtt for communication with OH. Maybe even something like a Shelly switch could work?
Something I only thought of after I posted, was perhaps a super-sensitive smoke detector probe that could be inserted into the inflow stream that could turn off the MVHR upon detection? Possible?
If you have a sensor that will detect smoke and change states (dry set of contacts that switch states, N.O./N.C. when smoke is detected) then yes that would work well.
