Hi folk,
I’ve posted an overview of the SensorPush hygrometers, here:
While not specifically designed for automation (there are better options for fixed humidity sensing in automated grows), it does have some features that are automation like that could be useful for curing, etc.
Since these are battery powered and wireless, it is very easy to drop them anywhere they’d be useful. Also, the OEM claims that they will be providing an API at some point to the device data such that it could be integrated into an automation control system.
