I've been dabbling with humidity sensing - using xAP, so integration
with Ian's relays is a possibility.
http://patrick.lidstone.net/ha/Current%20Project
has details of the basic telemetry board, which includes a humidity
sensor, albeit a pretty crude one. I gather dew points can be an
issue in horticultural/glass house environments, so perhaps this
wouldn't be suitable? I'd intended it to be used in the bathroom :-)
The board also includes ambient light, temperature, sound (for
occupancy purposes) and sub-cm movement detection (again for
occupancy purposes).
