I'm still running my 5 sensor DS18B20 nework on the Fibaro, becasue I have not gotten around to test it on the ESP8266 NodeMCU, yet. I have setup two NodeMCU's with DHT22 (temp & humidity), though and they are working well. Alos, tested the digital I/O with a 5VDC relay and that worked well too. The one draw back is the NodeMCU is a WIFI device, instead of Zwave or Zigbee, and I was hesitent to go that route. However, there aren't any real alternatives other than the Fibaro Implant.
The NodeMCU setup is a little more involved, but the hardware is better than the Fibaro. You can power it via USB. The Fibaro is very (too) tiny and the wires are very fine, delicate, and hard to work with. I don't see a practical reason Fibaro designed it that way. You will need an external 12-24VDC power source.
About your questions in the other thread...
- The NodeMCU is a small circuit board, that would need some sort of box. Currently I have two mounted on thin foam (pictures) with the DHT22's until my son can 3d print me a box. They are indoor though, so don't need much protection.
- Each NodeMCU should be able to handle multiple DS18B20, wired in parallel. I have not tested that yet. It can only talk to one DHT22 though.
- You can get the NodeMCU's with USB micro or C connectors. I used Amazon.com
These are the two DS18B20 sensor types I was able to get to work with the Fibaro. Several others did NOT work. Note the sencond one is a 6", SS, NPT fitting that went in my pool filter to monitor pool temps.
