Marmony Wireless Thermostat and Switch

Hi All,
looking for a bit of advice - Have any of you come across the above thermostat and 240v power socket switches? it’s used to control an electric wall heater.

It seems to use the 433mhz band to talk (one way - thermostat to switch) - Just seeing if i could bring the control into Openhab somehow but thought I’d ask around the forum first to see if anybody has had any experience of them before.
