I am new to OVO having been migrated from my previous supplier. I have found the OVO forum useful already, but does not solve my problem. My meter did have a T2 antenna fitted and was lighting up all the indicators except HAN. (We have no gas)Which I have discovered on this forum means that the meter was not commissioned. Subsequently a technician changed it back to one without an external antenna. Which of course does not work and SW lights up and the WAN lights every one second. Any ideas.Â
