Smart Meter not reporting and event 8154

Reed_Richards

My smart meter has not managed to communicate any half-hourly data since 20th July and this is bad since I am on a Time-of-Use tariff and use very little day-rate electricty at present.  The WAN and HAN lights on the comms hub flash together every 5 seconds so the comms hub thinks it is communicating normally.

The smart meter has an event log and the last "standard" event recorded was  Event code 8154 at 18:15:41 on 20th July, so the date corresponds to the start of my problem.  I looked this code up and it means:
 "Immediate HAN Interface Command Received and Successfully Actioned Mandated"

Can anyone with a smart meter tell me if that is the normal response to a data read request?  Is your last "standard event" today or yesterday?  Can anyone with a smart meter tell me if their "standard" event log shows anything other than 8154 events and how recent the most recent one was.

Edit: 8154 is supposed to be a HAN request but I don't have a gas meter and my IHD was off for several moths until 1st August so  there was no HAN.  I have been using the IHD since 1st August and it reads data from the meter perfectly well.

I had an 11 day outage in March 2024 and the missing data then was never recovered but this outage is lasting longer and is still ongoing.
