Hi, is your PROs Ring light lit? If not it’s a power issue so all data you are seeing in the app is historical. You may need check your power supply and transformer to the PRO, or it can ultimately be a failed unit.
'The PRO relies on constant quality power to ensure that it’s internal fixed battery and capacitor circuit are fully changes - ready for a button push as well as smoothing out small power fluctuations that allow it to record 24/7 into its few second buffer. The Power fluctuation can be magnified if an existing Bell unit is used as this can pull a high % of the available power from the supply (shared if using the Bell units transformer) when it chimes/rings.
Power issues initially show up as either a failure to initiate a cloud connection (and recording) after a button push, or no power at all. In the first instance, the PRO looks fine, but when the button is pushed the Ring will probably sound, but the light will go out. This indicates that the internal power has been drained and it goes off line. Within a minutes or so it can be back online and then Ring light is back on. Gradually this period will lengthen until the battery dies completely.
Why does ten internal battery die? Well various issues can affect it, but the quality of the power supply plays a big part as does the number of Ring events.
No Ring light would indicate a power issue, and it could be a failed device as above, or it’s a failed transformer/power supply to the PRO. Transformers can and do simply fail.
hope this helps in an understanding of theses issues. Many people don’t realise the PRO has a small onboard battery and how important it is.
