Rules

If a Red LED while Off and Blue LED while On is desired paste the following rule into the Tasmota console. If you want opposite colors, edit the template in the configure template screen and transpose Led_i with Led and vice versa. The "i" stands for inverted. Copy the below rule as one line to the Tasmota console:

Rule1 on power1#state do backlog ledpower1 %value%; ledpower2 %value% endon
on power1#boot do backlog ledpower1 %value%; ledpower2 %value% endon

Activate the Rule with

Rule1 1
