Hildebrandglow - Smart Meters - SMETS2

[JulianDH (Julian Hall)]

I might have missed something but I already have that figure in my energy page on HA. I am using following

Hildebrand Glow IHD MQTT

[alexhk90]

Listening to the MQTT messages ( “glow/[redacted]/SENSOR/electricitymeter”), I don’t see any of these cumulative cost figures, only the unit rate and standing charge for costs. Though as you say there is an option to display in money on the device itself, so perhaps you could try asking Hildebrand/Glow support if they could add these values to the MQTT messages?

The structure of the MQTT message is shown at the end of the official post here:

Glow — Local MQTT

(It mentions at the end there may be suggestions from the community on new things to add.)

@JulianDH

Hildebrand Glow IHD MQTT

was that repsonce for me ? if so can you expand?

[tomcoleman]

i have emailed them they said check the API

[tomcoleman]

not much luck!

I have monthly data available from my MQTT readings on the Glow IHD.
The firmware is on V1.9.0.

[alexhk90]

Interesting, thanks; I’m still on “App firmware 1.8.12” as I don’t have my Glow IHD connected to the internet - I’ll try updating to see if it starts to include the monthly/cumulative data on the MQTT messages.

[alexhk90]

Updated to latest firmware “App firmware 1.9.1” but my MQTT messages still don’t contain the cumulative data for cost (£), only for usage (kWh); for example (data values redacted, but shows the structure/fields available):

Did they provide a link to the API?

[SolarSurfer (Dirklee)]

This is mine …

[alexhk90]

Thanks; it looks the same - it provides the day/week/month figures in usage (kWh), but not in money/cost (£).

[BertrumUK (Neil B)]

The MQTT data is just the live data from the meter showing usage, and the unit rates. The cost is never shown on the meter as the app or your provider use the usage data and the unit rates to work out your energy costs.

I use NodeRed to use the usage data and unit cost data to give me the total cost of usage.

Im trying to install the integration by @HandyHat but its not pulling in any data - the bright app shows the data just fine.

I do not have Glow CAD (yet) so wanted to test the API only integration.

Is it still working?

[johnBoy (john R)]

I’ve given up with the DCC version. (No Glow CAD).

I did get daily data through March, but the data dried up towards the end of the month and none has been received since.

I’ll persue it no further.
It looks like you need the Glow CAD for any reliability / stability.

[alexhk90]

Good point - we do have all the data (as long as it was recorded for the whole time period) to calculate these downstream. For example, in the HA Energy Dashboard, although those numbers aren’t (yet) available as entities for usage elsewhere:

Using values of energy management in dashboards

I love the new energy management feature as it is very similar to what I am already using (though significantly easier). As I use some features in existing dashboards I was wondering how I could use the values in existing dashboards without the need to use the energy cards themselves. Would it be possible to extract those values from the database or something? See below an example which basically shows the energy consumption since midnight. [Screenshot_20210912-075321]

I do think it would be nice if we could get the cost figures that the Display/CAD already calculates over Local MQTT as well, so I’ve posted on the official Glowmarkt/Hildebrand forums here:

Money day/week/month cumulative total data via Local MQTT?

[ha_anton (Anton)]

FYI: Just checked the Hildebrand shop and the CAD (w/o screen) is now available from their shop.

[WhimsySpoon]

I have one, but it’s currently awaiting collection for a return as it doesn’t reliably power up.

When it did work, it was very good and I’m looking forward to receiving the replacement.

[alexhk90]

Is that a SMETS2 CAD? I can only find a SMETS1 CAD and the Display/CAD (both SMETS1 and SMETS2 versions).

Glow Zigbee CAD for Smart meters

However…

" Currently only available to customers on our Waiting List who we have notified; we are offering the device to the people who’ve been on the list for the longest."

[WhimsySpoon]

That’s the one I have. There’s a dedicated custom integration to get the local MQTT data from it and into HA.

The current power usage updates every ten seconds (faster than my Shelly EM) and it was accurate and reliable.

Unfortunately the only issue I had is that it wouldn’t always power back up properly once disconnected. When I received it, I quickly plugged it in to get it working. The following day I unplugged it to properly locate it and it just wouldn’t power back up. After repeated attempts, it eventually started working again, but it didn’t seem right.

Hildebrand’s support have been brilliant and immediately offered to collect and replace the device (which they’re now doing tomorrow). I’m looking forward to getting the replacement and having it back online.
