TH16/TH10 as switch only
* **Please explain your feature request in a one or two sentences.**
Hi, 
It would be nice to have TH16 as a simple switch, without temp/hum sensors enabled. 

* **Is your feature request related to a problem? Please describe.**

If sensors are not attached to TH16 or data they supply creates misinformation.  

* **Any particular eWeLink devices that this relates to?**

Any TH devise. Including THS :) which no one seems to have except me :)

* **Anything else?**
