Just fitted my eufy wired doorbell to existing wires. The consumer unit contained a transformer, which outputs 8v. Eufy says the doorbell will require an 16V to 24 V supply.
The doorbell works fine, when I do the Eufy check to see if the power is correct for the doorbell, it says all okay.
I know I should be very happy and okay to carry on, I’m just checking to see if I’m missing something?
