Good question, @stheobald! As the Ring Smoke/ Co Listener connects via communication with the Alarm Base Station, much like the other Alarm devices, thus it can certainly use the signal from the Range Extender. The Range Extender acts as an extension of the zwave network, and will help for connection. Keep in mind, a kitchen is a location with many interferences (appliances), so placement will be key. Check out our help center article for more information about zwave, and the Range Extender manual for more information on connection. I hope this helps!
