Previously had a smart meter with I h d and it worked perfectly. Got bulb to change the previous smart meter over to the latest smets 2 as the previous smets one went dumb. Since have the smets two installed it’s so hit and miss it’s ridiculous. It gets stuck waiting for data tried resets on the unit and running the battery down. Now it’s just blank waiting for data. If it’s not going to give you reliable it might as well go in e bin. I have full signals showing and even stuck it on top the meter itself. Smart readings are going to bulb but the I h d is useless.
