I understand your frustration and the stress of an unsettled household, but Hubitat just started shipping in January. It's still very much a work in progress. Vera and SmartThings both have many years of development under their belts. No offense intended, but it's a bit much to expect that they should already have all the tools anyone could want and all the drivers for every device there is, even devices that are 5 years old. Also, you're just 4 days into this. I didn't feel my setup was even close to what I wanted after a month, and I had experience with SmartThings.
Just like SmartThings (which is where the founders of Hubitat started), you are the "Tweaker Tool". As @bertabcd1234, I and others have suggested, you can typically modify groovy code from SmartThings to run on Hubitat with little to no effort. If you get stuck, you can ask for help and you'll get a lot of great advice. Sometimes you'll even get a tweak done for you. All depends.
Here's some guidance as a start, that should help you understand what things to look for and change when porting groovy code from SmartThings to Hubitat. I'm not a coder either, but I would suggest at least familiarizing yourself with groovy code a little bit. It's going to make the transition easier.
You are in the UK, is that correct? There are already many Hubitat users in the UK, Europe and Australia. Many SmartThings users in just about every country where those devices you have would be popular. Try asking on the SmartThings forum about the device. The terminology is DTH on SmartThings. Just ask for a DTH for your devices and see what's available. If you find something more appropriate than what you've found so far, it would be a good base, or maybe a perfect fit for Hubitat.
Just trying to be straight forward with you about the reality of the platform. Good luck and do feel free to call on me. If I can help, I will. If I can suggest something or someone that might be able to help, I will. We're all on the forum (most of us anyway) because we want to learn and help each other.
