Since a few days I received my Homey-Pro.

I have several 433mhz devices, Smartware and Trust Smarthome and experienced some issues.  
Switching on/off the swimmingpool pump (KuKa/Trust AGC-3500) also switched on/off the Espresso machine (smartwares SH5-RPS-36A).

This did not happen before on my Old Homey.  
Did anyone else experienced this aswell?
