I have my inlet, extraction and air movement fan all connected to a programmable 4-way that can be viewed and changed remotely. The functionality is good, in theory, but the reliability isn’t. Sometimes one of the sockets will ‘stick’, so I’ll return from a day out to find that the extraction fan of the inlet fan is still running on its own. Not only for wasted electricity, but the inconsistency of 1 of the fans staying on too.
I am aware of the twin fan controllers like the SMSCOM for the inlet / outlet, but is there something on the market (reasonably priced) that enables you to plug in x3 or x4 and have the ability to control?
