Thanks @Peter-Loeffler !
I think I'll dive into mqtt than!
As I can see Homie is only for sensors. I use mySensors to control my rollershutters.

Hi!

I've upgraded to OH 3.1.0 from OH 3.0.x

Installed openhab-transport-serial and openhab-core-io-transport-mqtt in Karaf console with:

feature:install openhab-transport-serial 
feature:install openhab-core-io-transport-mqtt

Tried to restart mysensors binding:

openhab> bundle:restart org.openhab.binding.mysensors
Error executing command: Error restarting bundles:
	Unable to start bundle 29: Could not resolve module: org.openhab.binding.mysensors [29]
  Unresolved requirement: Import-Package: org.apache.commons.lang; version="[2.6.0,3.0.0)"

Checked that only org.apache.commons.lang3 is installed:

openhab> bundle:list org.apache.commons.lang3 
START LEVEL 100 , List Threshold: 50
ID │ State  │ Lvl │ Version │ Name
66 │ Active │  80 │ 3.12.0  │ Apache Commons Lang

Thanks
