power supply for Ring Intercom

Honestly, I was sure that Ring would draw power from the existing intercom. Instead, it works only with a battery that has to be removed to be recharged. This is an unconscionable flaw. In particular, I just installed it for a bedridden girl who lives alone just to help her autonomy, and I was forced to tell her that every so often she will have to ask someone to remove and recharge the battery! Do you have any plans to produce a power supply that will allow for a stable power supply?
