I saw it advertised on strainly, too. Sounds like it.
Would be interesting to play with one. Basically, wifi + temperature + humidity. Light is probably an on/off measurement. VPD is simply performing some math on the temperature and the humidity.
The advantages appear to include a nice UI, tracking, and alerts. All integrated. It is unclear if the API is open to allow integration into a larger control system, eg. providing a data interface API. Or, if there is a “cloud” requirement.
Personally, wouldn’t work well in my application, curing in jars. The smaller devices are applicable for that. For a grow-areas, it’s interesting. Need to know more.
FWIW, calculation of VPD is relatively straight forward with the information that the sensor push gives you. Just needs the temperature and the humidity. For instance,
Eventually we’ll have the framework here for a significantly more advanced and open version. Topics tagged sourcecode
