Home Automation app Hive controls my heating, hot water and lights. I’d like to be able to track the time that these are on.

It would be useful to see what the effect of the the outside temperature and light has on the usage of gas and electricity used.

Hive has connections to Google Assitant, IFTT and Amazon Echo.
