I can only think that the resistor in series with the ring is to produce a voltage drop.
Ring doorbell pro voltage dropping.
This article will tell you how to connect a ring doorbell directly to a low voltage 8 24v ac transformer.
Video doorbell pro voltage dropping.
To check the voltage of your ring pro open the ring app select your ring pro and tap device health.
I think using the bypass on the pro power kit v2 helped.
Next morning i check and no power to the doorbell.
I wish i knew why this cycle occurs.
The ring video doorbell can only be connected to an ac transformer.
The doorbell pro stayed on.
Applies to both ring video and ring video doorbell 2 states that you must splice in a 25 ohm 50 watt series resistor.
For further insight on proper voltage in any specific environment we recommend contacting our support team.
The voltage seems to consistently drop to somewhere between the very high 3890 s or low 3900 s then auto bump back up to somewhere in the 4 000mv range sometimes up to almost 4100mv.
For ring pro to function correctly the voltage needs to be at least 3 700mv.
Some important facts for people planning on using this optional alternate configuration for their ring video doorbell.
Even after all this time effort and expense the voltage drops consistently every day and then the doorbell pro goes offline every few days.
To check the voltage of your ring pro open the ring app select your ring pro and tap device health.
If you can confirm suitable input voltage using a multi meter at the ring pro 16vac with the probes on the terminal screws then push for replacement because it s only going to get worse.
It s down to 3995 today.
The flow of voltage is dependent on many things including but not limited to length of wire run gauge of wires existing chime kits transformer output rating resistance and even in app settings.
Thankfully i have the chime pro since my existing doorbell is now bypassed.
And then the process starts all over and the product fails again.
Called electrican and he comes out unscrews the doorbe.
Dc is not supported.
I m happy to report the doorbell hasn t missed a beat.
Ring pro works fine for a couple of events and then stops working your ring pro requires a power source that supplies a minimum of 16 volts ac.
Recently installed by an electrican was setup and working fine around 9 at night door bell dies.
The voltage reading in device health corresponds to the level of charge.
My voltage dropped to 3898 yesterday and then briefly jumped to 4005.
I can t seem to get any explanation for it from ring.
