Hi
It's really the ease and adaptability that it seems to have. It's just like you said it's not primarily for saving money.
Is the hive not just gas. ? I have oil heating
Opentherm will be a requirement on new boilers soon, the stat will control the modulation of the burner and make a real saving. Nest supports opentherm and it will be more useful than switching it on with your phone
would you care to explain the possible enforcement of that type of stat kayos ?
ive read the quick guide from here
https://www.opentherm.eu/why-opentherm/
from another source the info just points to this quote
there has been a noticeable period of product development growth and intense marketing activity around smart control devices, which can enable even greater energy and cost savings.
i beg to disagree the only saving is down to there owners or there settings on there boilers/ stats or radiator stats
