Mysensors sensor works with HA but actuator show up as batteries in HA

Hello, I am using HA on RPi connected to a serial gateway ( Sensebender Gateway).
I have hooked up various sensors Sendbenders sensors and my own sensors which work perfectly well in HA.
My problem is I can’t get any actuator (example Relayactuator in examples/Mysensors Arduino library) to work in HA. They always register as batteries. Is there anything special to do in HA to control my Relay with virtual button or other ?
