In the new year I’m getting my bathroom’s refurbished, and I’d like to get a “smart” extractor assed as part of this works.
I can see a few topics on this but, I’ve seen that AirFlow so the ICOSmart extractor, that has Bluetooth (and an app), there’s also additional modules for it, I’d get the humidity, timer and motion as I don’t see the point in any of the other combinations.
Does anyone know if there is any form of integration with HA for this? I’d prefer to go down a simple slick solution like this rather than adding additional relays etc. but I’m kinda open to suggestions/feedback etc.
Does the extractor fan in your bath controlled by a wall switch?
If so, I personally would rather recommend you find a good but dumb extractor fan, with correct size / flow / power consumption / noise level… and then use a smart wall switch (or smart relay behind the switch) to control the fan.
… so that you don’t have to limit your choices of any extractor fan. and maybe have to compromise…
And then use a separate sensor for humidity and motion… again you don’t have to limit your choices.
Total cost would probably be smaller, and you gain a lot more flexibility.
For a smart bathroom exhaust fan setup integrated with Home Assistant:
Fan Recommendation:
Use a dumb multi-speed fan like the Panasonic WhisperGreen Select or Delta BreezSignature. These fans are quiet, efficient, and compatible with external controls.
Smart Wall Switch:
Use Girier Zigbee 3-Speed Fan Switch Module or Leviton Decora Smart Fan Controller (Z-Wave or Wi-Fi) for fan speed control. Both integrate well with Home Assistant via Zigbee or Z-Wave.
Sensors:
Pair with Aqara Temperature and Humidity Sensor or Sonoff SNZB-02 for humidity-based automation. Add a Philips Hue Motion Sensor for occupancy-based triggers.
Home Assistant Configuration:
Use Zigbee or Z-Wave hubs (e.g., Conbee II, Aeotec Z-Stick) to connect devices.
Create automations to adjust fan speed based on humidity and turn the fan on/off based on conditions:
AirFlow iCONSmart:
Limited integration options. It lacks native Home Assistant support. A smart switch and sensor setup provides more flexibility and reliability.
Alternative Smart Fans
Claims to work with googlehome and alexa built in
(no guarantee that it will integrate into home assistant perfectly)
Recommendation: Avoid limiting choices to Bluetooth-only fans like iCONSmart. Opt for a flexible, modular system with a smart switch and sensors for better integration and cost-efficiency.
Great advice thank you, and that does make a lot of sense, I was thinking of trying to make life a bit easier, but actually as you say this limits the flexibility etc.
Hi Jerry I do have a question here. Are we sure that the
and these switches would work together?
… because I thought the red wires from the Panasonic WhisperGreen are low voltage signal wires and not 120 nor 240VAC, and not for any 3- or 4-speed fan switches.
I dont like cloud products but… 120v dosent have allot of 3way wifi switches it appears. theres literally thousands of ways to do this tho and you could even use dumb fans and dumb switches with only hidden relays and micro controllers.
I dig deeper into this Panasonic, and turns out the 2 red wires would have to go with a regular on-off switch… so that you can either bring the fan from standby to on, or from low to high - you would have to pick one and “program” it accordingly.
Around 4:20 - “they are not designed to carry current; do not attach power to these conductors”
I digress.
To OP, the general recommendations here still holds. Find a good quality bath fan you like, and do on-off smart switches (along with smart sensors) to control the fan.
Multiple-speed fan smart switches are typically for ceiling fans (with AC motors), so I would recommend we stay with on-off smart switches.
