@mutmut Good question: both speak OpenWebNet, but they are not the same installations, so no duplicates.
- Legrand In One CPL by @XDECO: In One modules via powerline, through the USB 882 13 interface (serial port exposed as TCP by socat).
- BTicino MyHOME (published here: Intégrations Home Assistant les plus populaires → candidates pour des intégrations externes Gladys - #478 by lmilcent): MyHOME / MyHOME_Up installations via an IP gateway on the local network (MyHOMEServer1, F454, F455, MH201, MH202…). It does not communicate with the 882 13 and does not know the In One modules.
Both can therefore be installed side by side, each for its own system. Well done @XDECO for the work on In One, and for the frame captures on a real installation!
