I got my Z-Relay working with some help from Heatit support.
Temp input 1, energy and power works, but still no voltage or current.
I had to re-add my Z-Relay without S2 (Use 00000 as PIN) and tell told me to change my group association to 1.1 on group 1 and leave the rest blank. BUT, it worked with just leaving every setting as is.
Just enable the input 1 sensor, and it worked.
