Capacitive Rain Sensor
The usual cheap rain sensors from AliExpress and other platforms have some disadvantages. They work by conductance so the electrodes must have direct contact to the water. Dirt and aging can influece this, the water conductance may differ depending on what a raindrop collected on it's way through th...

Re: TEMT6000 Light/Lux sensor supported?
It's an analog sensor so it gives a voltage that follows the brightness.
You may use the analog input plugin.
With a bare ESP8266 it might need a voltage divider as the input should be in the range of 0....1 V.
On WeMOS and NoceMCU this voltage dividere is already there in most cases.

Check for Rx & Tx. They might be swapped.
Second, test for GPIO16 <-< SET. 10KOhm resistor attached?
If the resistor is in place, just leave the resistor connected to 3.3V and SET, open the connection to GPIO16.
This sets the sensor to permanent running.

If something with rules does not work the GPIO16 might be permanently on "0" disabling the sensor.
