Smart thermostats

Sample prices for fictional thermostats. Merit rank is printed on the name. The headline price is the lowest in stock.

A thermostat ranking will rest on control, how clear the schedule is, listed boiler fit, and what the app stores. These rows are samples so the table can be reviewed. They are not a verdict on a real model.

Sample fixture, not live shop prices.

Filters hide products. Sorting changes the order on screen. It does not change the printed merit rank, or which shop has the lowest in-stock price.

4 of 4 shown. The printed merit rank does not follow the sort. The headline is the lowest in-stock price.
