I have 3 of the Almond 3 configured as a mesh, yesterday I notice connectivity issues in my Master room, then I found out that one of the nonprimary devices loses the IP, the app shows as the unit is connected to the network but it doesn't have internet access. There was no way to reconnect this unit, not even unplugging the power. the only option was to force the manual remove of the mesh configuration, factory resets the unit and adds it again.
First, It will be nice to have some sort of notification when a unit loses the connection, also some sort of IP reset, IP Renew option will be more helpful to troubleshoot and sold this kind of issue.
