Playing on the “Switch + sensor” idea from Light Switch + light / motion sensor …
I would be interested in a switch with a built-in humidity sensor to manage a bathroom exhaust fan.
This might not be a practical idea for a variety of reasons…
- sensor accuracy
- safety of a “water” sensor in a AC switch
- whether “high” vs “normal” humidity can be defined in the real world
BUT… here’s the pitch :
Novel Operating Modes (beyond normal scenes, timer, etc. from Lights Out et al):
-
Single Shower Mode: Tap on, Humidity monitor off.
- Tap to turn on
- Snapshot current humidity.
- Stay on during a shower
- Monitor humidity increase of
>= X%
due to shower
- Monitor humidity increase of
- Auto-off when humidity returns to normal
- Monitor humidity decrease back to baseline
+/- Y%
due to exhaust fan after shower’s over
- Monitor humidity decrease back to baseline
- Tap to turn on
-
Humidistat for a exhaust fan/dehumidifier
- Auto-on when humidity above a set point
X
- Auto-off when humidity returns below set point
- (perhaps more feasible in changing indoor humidity: auto-on/off for a rapid deviation compared to a monitored background measurement like an hourly average?)
- Auto-on when humidity above a set point
-
Humidistat for a humidifier
- (e.g. plug in humidifier on a switched outlet)
- Auto-on when humidity below a set point X
- Auto-off when humidity returns above set point
