So I’ve implemented a couple of Fibaro single/dual relays throughout my house to control outdoor lighting, I now want to move onto my next project: Smart control of bathroom lighting plus loft extractor fan.
We have a Vent Axia unit in our loft that is continually running and when humidity increases it in turn cycles up through the settings to extract moisture quicker.
I have a couple of issues with this setup (previous owners added). One, with it continually running it is extracting heat from 4 rooms, master bathroom, utility, downstairs toilet and ensuite, and two, it probably doesn’t need to be running continuously.
What I’m hoping to achieve (starting with the master bathroom) is :-
Switch on the master bathroom downlights when motion is detected and a certain light level is reached (no point in turning them on for the sake of it). I can achieve this with a relay behind the light switch and a motion sensor.
When a certain level of humidity is detected, switch on the loft extractor unit and switch off when it drops below a certain level.
Switch off the master bathroom downlights when no motion is detected for x minutes.
Are there options available to get this working in Smartthings? I believe there are some multi-sensors that combine motion, humidity but do they offer lightness/darkness detection?
To complicate this setup more, I’d be looking to extend the motion/humidity options to the other three rooms.
Lastly, will sensors be up to the job in a bathroom that can be 100% humidity? I’d ideally like something permenant that I can place within the ceiling as I can access electrics up there to wire it up.
