Wow! Thanks for the information, that is really useful.Yes. I have the Octopus Home Mini + the Octopus HA plugin. HA fetches data from Octopus once a minute [but - to keep it relevant to this thread - not gas readings as the gas meter is battery powered].
I have an Octopus Home Mini too. But haven't yet had the time to configure the HA plugin. My gas & electricity meters were fitted in Nov last year. Do you think my gas meter is battery powered too?
