looking for a wireless thermostat system for Bosch Greenstar 30i boiler

Despite all the replies I'm still not clear why there isn't a snap in controller to replace the electromechanical one. Surely it's possible?

When you mention Hive do they actually make something that replaces the electromechanical timer in the Greenstar 30i?

I wrote this previously but I'll write it again in more detail.  To access the controls and your optional electromechanical controller there is a hinged section of the case which you pull down.  So when the case is closed for normal operation
any controller that plugs directly into the boiler is inside a metal box.  A metal box will block the wireless signal that the controller needs to communicate with a wireless room thermostat.

So you mount the controller on a wall and run a wire from the controller to the boiler; it's very simple.

The hinged panel which you pull down is plastic. The area where the electromechanical timer clips in is plastic.

Reading the install manual for the MT10RF its simply not a home user install, You need to be gas safe to remove the main cover to plug it in, no mater what version you end up going with, smart or like for like replacement.

So does it just clip in to replace the old one?

There's a link to the manual in markin's post above. It's a little bit more involved than just clipping it in. Look at them and see what you think.

I see there are various other options for timers and thermostats. Make sure you chooe one that fits your specific Worcester boiler, they're not all identical.

Could I suggest a couple of options to avoid / mitigate the risks associated with DIY gas work?

Assuming you have your boiler serviced regularly then you could get the parts, install the wall thrmostat part and get the service engineer to install the boiler part for you as part of the next service. If it's just a question of plugging it in the cost should be minimal, and if you know your service engineer may even be free.

Another option, if you absolutely must go down the DIY route, would be to do the installation just before the next boiler service and then at least you'll get it checked out as part of the regular service without any cost.

Apparently you don't need to be Gas Safe to do this work on your own boiler:
