After installation we had an issue where the IHD sat there for over a month saying "Waiting for data..." after a power cut ran the battery dry. However it eventually came back again and started registering consumption.
After reading my latest bill there is only a summary of electricity consumption which is odd - we have gas but only for our boiler; nothing else. However there is no sign of gas consumption on the bill.
To my horror I've looked back through the meter readings and the last time our meter reported a gas reading was the month after it was installed! It has submitted NOTHING since then according to the meter reading summary. I've not been chased for any meter readings as I would have been normally on conventional meters, so this problem has gone unnoticed. This needs sorting out and EOn cannot put their full faith into the reliability of these meters automatically sending readings. If an automatic reading is not acquired from a smart meter, then a notification should be sent to provide a manual reading
In addition I also noticed another thing to do with tariffs. Having a smart meter fitted seems to disqualify you from the cheaper fixed tariffs. The smart meter tariff I had been on had disappeared, and all of the other tariffs offered (which were all smart meter only), were considerably more expensive.
