My ring doorbell 2(bought second hand) has recently stopped recognising as being hardwired so I have to charge the battery every few weeks. [br]
the transformer is rated at 24v AC 3A(72vA) and I am still reading 24v AC at the terminations when powered up so the transformer is working as expected. [br]
I can only assume something has gone wrong internally but obviously the device is outside of any warranty so it’ll be down to me to fix or repair.
