Had them installed last week. Check out the green lights on the meter, according to the engineer if they all flash in unison every 5 secs or so, its all working correctly and pinging data back to the central hub, which feeds Bulb. If you’ve only got an elec meter then I think less lights will flash.
The main benefit to me is never having to access the meter every month to keep our pricing schedule in check, we always use lower than their estimate. The rest I can do on the website.
As an aside, I think bulb have some billing issues with the new SMETS2 meter roll out. I’ve been automatically cretitied all the actual readings energy costs since joining and will be correctly invoiced again at some point in the next week or two. Bulb couldn’t really explain the issue other than saying it’s glitch they’re in the process of resolving.
