I’m looking for a cheap ZWAVE humidity sensor for my bathrooms & basement. The reason I want ZWAVE is that all of my wall switches are Leviton ZWAVE products and I’m 99% sure they all have ZWAVE repeater function in them. The bathrooms are close enough that I could use a ZigBee device, but I’d like to keep standardized. Main goals: two bathrooms with smart switch already installed on fan to turn on when humidity gets too high and monitor basement humidity and inform me when it gets too high. Something that is small and unobtrusive and battery operated is preferred. Also, I would possibly like to trigger my new RHEEM Econet thermostat to lower humidity if any of the monitored zones away from the thermostat get too humid, but that’s another project.
So far, the only thing I’ve found that meets my cheap option is the Centralite Temp & Humidity Sensor for $24.99 on Amazon. It’s downside is that it uses ZigBee and is unlikely to work in my basement. I also like that it uses lithium coincells instead of AA or AAA batteries which have a tendency to pop and corrode the battery plates in a device. I’d love to hear about other devices that people have used in the $25 range plus or minus that are ZWAVE.
