IHD Waiting for current data

For three days the IHD says its waiting for data. There is nothing wrong with the house wifi Please explain why and what I can do?
Thanks

Hi @BobH_22
It’s not your WiFi which the IHD uses to get data from the Smart Meter so that won’t be the problem.
Does your IHD show two signal strength indicators (one is for WiFi and one is for the HAN connection to your Smart Meter)?
If it is only showing WiFi connection and not HAN connection then try moving the IHD closer to your smart meter and see if that helps?
