Group Warnings

So I have 3 Ring devices that I thought I would group together then try and mute all abnormal uploads.  However I can only add the mute to alarms if the devices are not grouped, or have i missed something.  Unfortunately ring seem to change their IPs a lot, so i cant keep adding mute for each IP that comes up.

I deleted the group, added the mute, then recreated the group.  Any ideas on a better way of creating group devices and warnings.

Thanks

Andy
