I’m having very poor results with the duo cam doorbell as an upgrade to my existing Wyze doorbell cam.
I connected the duo cam to the same hardwired supply used by the original Wyze doorbell. It refuses to charge its battery. It is also extremely unstable in terms of its ability to stay connected to the cloud, both the web view and the Android app are constantly losing connection.
I’ve verified the supply voltage with a meter, also replaced the transformer to eliminate that as a root cause. The power is supplied directly, there is no old chime in the circuit.
I’m guessing this unit might be super fussy about the supply voltage, but that seems an undesirable functional characteristic for something being wired into a doorbell circuit (one which ran my original Wyze doorbell cam for years).
