@JMRewop 60 in the water tank means that temperature in the (single?) circuit is even higher, likely not very energy-efficient. Condensing gas boilers work better in much lower temps, heat pumps...

@JMRewop Water tank heating should definitely be temperature-based, not just time. My boiler switches the room/water heating circuits automatically with its internal valve, while yours seems to be...

@JMRewop Nest is totally redundant when you want to have something more capable. You can't turn on the boiler directly because it's not exposed to IoT system yet. Instead, you manipulate Nest...

@JMRewop Using Nest Thermostat for this isn't optimal, as you manipulate its temperature setting instead of controlling the boiler directly. I'd suggest to replace it with simple NO/COM smart switch...

@richrobuk Easy, if you have any experience e.g. with booting Windows installer, entering UEFI settings etc. - just basic computer literacy. I suggest cheap low-power Lenovo, HP, Wyse, Fujitsu thin...

@richrobuk Just use Home Assistant for boiler automation, as of now it likely is the only possible way until TP-Link improve external integrations. Heating status is broken in Google Home, broken via...
