Will adding VD3+ battery last longer if use a Chime pro to reduce RSSI

Hi @L1111. It’s possible that lowering the RSSI and improving the connection your Doorbell is receiving can help the battery life. With a higher RSSI, the connection is more strained which can cause the Doorbell’s battery to discharge more quickly, but it may not be a very significant difference in battery life overall. You can read more on RSSI and what it is in our Community Post here.
