Smart Heating Solution for UK Holiday Home

After spending years in SmartThings, I’ve finally made the switch to Hubitat and couldn’t be happier with the move to HE! I’m currently working on a project to fit out a wooden holiday home in the UK, and I need some advice on the best way to control the heating. The main challenge is heating three bedrooms and controlling a couple of towel rails. I’ve considered using wall-mounted oil radiators, but I’m not sure how to integrate them into my smart home setup. I’ve looked into a few options, like using smart devices that integrate with HE or setting up a dumb radiator with manual temperature control. I’d love to hear if anyone has any smart ideas or experiences with similar setups. Thanks in advance for any suggestions!
