Unfortunately, no community app that integrates with Eufy is available. I think this is more of an issue with Eufy's proprietary system than with Hubitat.
A community member has written a driver that works with IObroker Eusec....ioBroker.euSec - An ioBroker adapter to control Eufy Security devices . I was able to get Eusec/IoBroker to run on a Raspberry PI. It does allow me to arm/disarm my Eufy Homebase using Hubitat Rule Machine, but I found the integration to be involved and cumbersome to say the least. If you are interested in going down this rabbit hole let me know and I can walk you thru it. It may not be the solution you are looking for since IoBroker does require an always on computer such as a Raspberry PI. I am not familiar with the Home Assistant integration for Eufy.
