• I believe that the smart meters always run on GMT - this is what I was told by our energy supplier. Certainly our Economy 7 off-peak rate is currently available from 01:30 BST to 08:30 BST (00:30-07:30 GMT) - this is confirmed by messages on the IH…

• I don't see why not - devices like this connect to the meter(s) over the HAN, which supports multiple devices concurrently. This is how a smart meter provided IHD and a Glow CAD are able to co-exist.

• I was interested to see that you are receiving data for a meterread request to the API - last time that I tried, admittedly a while ago, it was returning 'Not implemented'. I have just tried again myself, and am now seeing valid data, with the same…

• KS_Eric, although I believe that it is possible to build an MQTT broker using Python, it is more usual to run something like Mosquitto (a pre-built broker). You will need a system that will run 24x7, but you haven't suggested what platform you mig…

• Hi, I have access to our meter readings, but only via MQTT from a Glow CAD. Unfortunately I don't believe that Hildebrand can access meter readings from the DCC as their access is classed as 'Other user' and doesn't permit this - I had an email exch…

• Indeed, I was interested in seeing how much the CV varied over the month, rather than just having the average value given on the bill. And 1.02264 is a correction factor for temperature and pressure - the calorific value is in the range 37.5 to 43.0.

  in where do I find the Calorific Value Comment by mcockerell January 25
• I've been looking into this myself, and believe that the meter uses a constant value for the CV, which will not be the same as the monthly average value used by your supplier for billing. I have found the following page on the National Gas website w…

• The MAC address can only contain hexadecimal digits, so numeric zero (0) to nine (9) and letters A thru F - letter 'O' is not valid. Hope this helps 🙂

• I'm not familiar with HA automation, but don't think that a feed via the DCC will be responsive enough for this. I found the following on Github for a Hildebrand Glow (DCC) Integration add-on (https://github.com/HandyHat/ha-hildebrandglow-dcc), poss…

• I too am interested in obtaining electricity meter readings via the DCC, at least at month-end and ideally daily for a complete month? Is this possible? The documentation suggests that it should be, but I also receive 'not implemented' as the respo…
