In doing my research I found a few devices but only one that I could buy within the UK. The IoT controller is connected to the boiler PCB and through the controller you can access via its own built-in webpage so use if on a phone or computer. It came with the IoT controller as standard as well as the flue. The downside is that the UK support are no existent but as its a global brand its easy to find someone to answer your questions. Cost wise it was about the same as any big box mass sold items so for what it does, amazing price
Interesting. I wondered what boiler you have; is it possible to switch any condensing combi to operate in this mode? Would Opentherm or Weather compensation achieve the same? Any link available for info to the IoT device you mention?
