After a power cut, my IHD is not communicating with the smart meters, It re-boots every 74 seconds,
3 leds and “welcome to your new energy meter” etc This cycle is continuous all the time the power adapter is in use. Using the Bulb reset procedure had no effect. Bulb have passed it onto their smart meter team? The ordinary help people were clueless!
Previously the IHD froze, on that occasion I left it to discharge the battery completely, that was a fix at that time.
