Hi Amenomade,
Thank you very much for your help !! with your 2nd tuto (and Google translation), FHEM succeeds to recognize one of my Eltako FSB61NP (I will make the other afterwards). I would have to other questions if you can help me :
1- the commands of the device are inverted = it opens when I click on "closes", it closes when I click on "opens"; do you know if I can change this to the right way ?
2- my project would be that Home Assistant (which doesn't recognize my Eltako Triggers) ask FHEM to open/close the roller shutter; for that, I understant that :
- I need to create a MQTT broker (I have just done it on Home Assistant)
- I understant that I need to declare a MQTT on FHEM but :
2a) as FHEM will probably need to received and send some message, I don't know if there is a specific MQTT to install ? a client (it seems only to receive message) ? MQTT device ? MQTT generic ?
2b) do you know where I can find explanation on how to install and use MQTT on FHEM ?
Thank you very much in advance for the additionnal help!
