HA Newbie - Sonoff R5 Support

Hi,

I’ve dabbled with HA before but have put off migrating fully from Domoticz until now. I have a simple Domoticz set up which ive 99% been able to replicate in HA but I need a couple of scene controllers in a couple of locations. In the UK, it’s easy to get the Sonoff R5 and it fits where I need them, but looking at the SonoffLAN custom integration, it’s not supported locally, which I’d like to try to maintain. Is there a way to use this locally as a scene controller, or is there a comparable Zigbee 6 button controller easily available in the UK? Needs to be battery operated.
Thanks
