EcoRenovator - View Single Post - Temperature or Humidity control with Sonoff TH16

The dehumidifier was short cycling too much. The humidistat was cycling a bit too fast.

So, I went to Ebay and spent $16.41 on the 16 amp 90-230vac switch and the sensor.
The Humidity calibration is off.. Reads around 10% high. But it's usable.
Right now, it's cycling 9% between 47 & 56 percent RH in the basement. (per two sensors).
Using the built-in humidistat the cycle limit was 4 to 5 percent.
By using a 9% range, the off-on cycling is a lot less (at least with the current weather).
The run-time and power use might be starting to drop a little..?.

Anyways, the gadget works. You can also control heating or cooling hardware too, fans ACs, space heaters etc..

Plus, it can be used as a simple remote controlled relay using a phone or tablet app
with direct control or timer activated.
There is information online for reprogramming the Sonoff's chip to make it more versatile.
