I bought my S220 video doorbell 16 months ago and until now it has worked extremely well. The product details advertised Dual Power Options providing “Half a year of coverage from one charge or non-stop power supply via a wired connection”. As a result, rather than rely on battery power, the unit was hard wired in from the outset using the 24VAC transformer supplied with the unit.
My app now tells me that “Doorbell has turned off due to low battery”, how do I resolve this.
Hi, if you have a multimeter where you can test the DC voltage output of the transformer.
I would remove the camera from the mount disconnect the transformer wires and put the test probes on the two wires see what voltage you have.
Hi, I have just checked the doorbell with my multimeter and have slightly over 24v.
Just to clarify the supply was 24v AC. With the wires disconnected the DC reading is 0v
Okay, 24v AC is good. Do you know how to test for volt amps VA? You may have the proper voltage but the VA may be low to charge the battery.
Have you tried to manually charge the battery with an AC adapter and USB cable?
Just to see if it happens again ~ shut down due to low battery…
Hi,
Thanks for your help. The doorbell has been fully recharged via USB and is now working, I will see how long it lasts.
As for VA measurement, I am just a DIYer and not done this before can you explain the process for me.
Thanks
What you’re doing is using the multimeters 2 test leads in the circuit/complete the circuit to get a reading.
Don’t know what your multimeter options are but, you could probably leave the test leads where they are and select the proper settings mA~AC A~AC.
Here’s a U T video
Do you know the specs of your transformer, they are printed / stamped directly on it.
I did as you instructed and despite repeated attempts, I consistently recorded a 0.0 reading on the multimeter, picture attached with settings used.
Also find attached photo showing transformer spec.
If you did, then put the red probe into the 10A port on the meter and take another reading.
The VA may be too high to be read using the other port.
This is me testing a DC direct current transformer, but yours is AC alternating current.
Eufy specs their battery life based on 10 detections per dayand 30 seconds of recording per detection. If you have more detections or longer recording set, your battery won’t get the life that Eufy promises.
Also, your transformer has enough voltage, but the current supplied is pretty marginal if your detections are over 10 per day.
You can look up the number of detections in the Power Manager tab of the doorbell menu. You may have to run it solely on battery for a while to get good detection statistics as the stats aren’t accurate when its being continuously powered by AC.
