AliExpress / Alibaba - for low cost Home Automation - Warning

These are good.. just installed one in our upstairs hall bathroom.

Recommend a humidity sensor that's accurate?

I have several of these: They're very responsive, reasonably accurate, and work with Hubitat. The only caveat is that they're restricted to zigbee channels 15, 20, and 25. I have a couple SmartThings zigbee outlets that I use for power monitoring, but I don't know if they're rated to handle the high influx current a dehumidifier is likely to have when the compressor turns on. Zooz has an outlet that may be more appropriate for this use.
