So my issue is similar in that I have no existing doorbell or doorbell wiring and I do not have any space in my consumer unit. Need to understand whether I need to use the Power Kit and where I would install it if necessary
Here is what I have done
Bought the Ring Doorbell Pro which comes with the transformer
Wired in a spare plug that I rated to 3A for plugging into mains socket
Cabled to the transformer using mains terminals 5 and 6
Fitted the transformer into a junction box or single consumer unit
Ran a length of cable to the doorbell from terminals 1and 4
Wired to the doorbell
Powered everything up and it is all good
Doorbell showing over 4000mV on the App and it has been working fine ever since.
Do I actually need to use the Power Kit given I have used the Ring Transformer and my power is ok
