I have an oddly shaped main bathroom that has 3 entry points: bedroom, walk-in closet, and deck that all open into the bathroom. Room dimensions: 17’ top to bottom and 11’ to 12’ left to right.
There is a 4-way switch (4WS) that controls a flush mounted light (square light in pic). Scones over the vanity controlled by a dimmer (SD), a chandelier controlled by a dimmer (CD), and exhaust fan and shower lights controlled by a Zooz Zen30 double switch. All the switches will be either Zooz or Enbrighten. I’ve also noted areas where we have a plug.
My goals are to turn the lights on automatically regardless of entry point and for the lights to stay on while showering, soaking in the tub, or using the vanity. I also want to turn the exhaust fan on automatically based on the humidity. I assume I need multiple sensors to achieve this because of the configuration. Below are my thoughts and would love yours as well as Zigbee/Z-Wave device recommendations:
- I know I can’t get away from getting an mmWave Presence Sensor that covers the bathtub. I’m thinking of getting the Aqara FP1. I would love reviews on this and other recommendations. Are there models that you can wire directly (like a switch)?
- I know I need a humidity sensor for the exhaust fan. I’ve also seen others using it to indicate “I’m showering”. How reliable is this in practice? What is your recommended multisensor (motion & humidity) that I could use in the shower? I’ve seen some casings for sensors to make them “outdoor” safe. Would those work for indoor multi-sensors?
- I was thinking of getting a single motion sensor to cover the entry points.
Finally, what is best practice to combining sensors to indicate presence in rules? Virtual devices? Local variables in RM? Easily achieved in ML or RL? In an oversimplification pseudo code, I’d like to:
Trigger: Motion OR Presence Active
On: Bathroom Lights
Wait: Motion AND Presence AND Shower Motion Inactive (may add a delay)
Off: Bathroom Lights
Thanks for reading if you made it this far!
