I tested the Telis 1 remote on the RFLink Gateway with R40 firmware and within one meter I get the debug output as expected: -> Press Down 20;06;RTS;ID=e6a531;SWITCH=01;CMD=DOWN; -> Press UP 20;08;RTS;ID=e6a531;SWITCH=01;CMD=UP; In Domoticz when learning I also need to have the remote within 1 meter ...
