It has been a few days more now, but I carried out these steps.
I ordered the Ring AC adapter (24VAC). I received it.
Charged my Ring Doorbell 3 Plus battery completely (100% loaded).
Mounted the battery into the device.
Then I did the reset (Press button 20 seconds).
Connected the received Ring Doorbell adapter.
Then connected the adapter to the wall outlet.
In the app I see a green battery with a small lightning sign in it.
Tapping on this battery icon I get into the data.
I can see the bell is Connected, which is good. (Solar Status is not an issue anymore!).
However, after 3 days now, I see that the Battery level still drops.
It is at 92% already…?!
I wonder now, is everything going well?
I used my Digital Voltage meter and the power that is measured is 27V AC, so it appears that the Adapter works fine.
Do you have any advice for me please?
I start thinking that the Doorbell has problems with the charging circuit now…
Hope not but, fear is present…
Thanks in advance.
