Doing a google search suggests its in the MQTT message of the subscribed topic "glow/+/SENSOR/electricitymeter", however that doesnt seem to have LQI in it. Can anyone shed any light as to were I can find the LQI info. TIA

Kind Regards

Just about to send a 'bump' email too.

The Bright App says "Device is not reporting"

The CAD display is connected to my WiFi hub but reports "server is not available".

I have power cycled the CAD and reinstalled the App.

What should I do next?

I have four UniFi APs covering my home (channel overlap isn't an issue) and have tried moving it to another AP model and checked settings to ensure its not from the AP side and I cannot see any cause. The GlowIHD has an excellent signal as the nearest AP is in the same room and its the only 2.4Ghz device connecting to that AP.

Is this part of the firmware design?

Note: I did consider an Ethernet IHD recently but their dependency on online configuration was a showstopper for me.

Now I did change my WiFi APs a few weeks ago and this happened around a week later, however I'm not sure if this is related as every other device on my network (including many ESP8266 / ESP32 based devices) have been fine. I've also tried with a separate SSID that only the stick is connected to and WiFi Channels 1 & 6 (20Mhz).

The stick itself when I reboot seems to flash the WiFi LED green for quite a while, and eventually it turns to red.

From what I can see the actual stick is connected to the WiFi AP based on the APs logs. My router also confirms that it's online with an active IP lease too.

I can also see the stick despite showing red for the WiFi LED, that it's actively making DNS lookups to ntp and a subdomain that then is for Glow (.cad.sensornet.info) making me think it might not actually be WiFi related.

Any help with diagnosis would be appreciated.

However 12 hours later it got stuck in a loop requesting to join HAN and not being successful. That was 3 days ago, so not so impressed any more.

i have power cycled, opened up firewalls and had Octopus send a new join request via HAN but all with no luck so far.

i emailed @janeatglow via email a few times but have had zero response, which is quite disappointing. I hope I didn’t buy a brick.

Any ideas out there on how to resolve this?

Many thanks Marc

I was wondering if there has been a recent firmware release for these devices that is causing the issue or may I just be unlucky and have a potential hardware fault with it.

We've been having discussions with BEIS about the fact that some of you using MQTT have reported that you've recently lost your instantaneous export feeds.

This is not a policy decision - but apparently some

The second change is the IHD will join a default set of wifi credentials if the stored ssid/password is not available or the password is wrong - it is mainly for Glow customer services to provide support.

I am doing a small rollout over the next couple of days and a full release next week. If you are one of our beta testers you probably have it on already.

SMETS1 devices are being done first, followed later today by SMESt2.

I came down this morning, and noticed the time was displayed as 10.51. No buttons were responsive. So I unplugged the usb lead, and removed the batteries to try reset it.

But now it won’t come on at all. Is there a button sequence to force a hard reset at all?

Looking at home assistant, the last time it provided data was just before 11am on 16th September. Looking at the UniFi app, it dropped off the WiFi network around the same time.

Any help appreciated.

Is there anything I can do here or do I need to purchase a new one?

Specifically: the overall usage in KWh, and there are quite some discrepancies: EON reports 67,703 KwH wheras the IHD reported about 70419 KwH for the same day.

The gas volume is however about right (IHD, vs EON reading).

So this suggests to me that the calc the IHD is using may be different - perhaps the CV is different, and the approximation in the IHD is different ?

AI tells me that: "Your supplier, is required by law to use the actual, daily-measured calorific value for the gas in your region. The National Grid constantly measures the CV of the gas as it's distributed across the network...."

wheras the IHD (presumably) uses an standard factor for both temp and CV differences etc.

What actually is the IHD doing ? and why is it so discrpant from my supplier ?

If you are interested in testing it please email support@glowmarkt.com with a subject of IHD beta test from the email you have registered in bright.

When I look at the data being sent out via MQTT:

Import Today (sensor/electricitymeter/import/day) resets to zero at 1am, not midnight

I think this is a bug not a BST problem as Import This Week changes at midnight Monday morning. For me this week's Import this Week reset was strange:

23:53:02 - 127.9kWh

00:00:12 - 30.07

00:56:32 - 31.9

01:00:12 - 0

So it takes an hour to get to zero sitting at a random value and increasting on route!

Import this month is similar but different

23:51:10 - 174.8kWh

00:00:20 - 19.4

00:01:00 - 23

00:01:20 - 0

Unit Price (... /import/price/unitrate) has a different problem. My tariff changes 00:30 and 04:30, the unit price changes at 00:035:06 and 00:04:34:06 (00:35:13 and 04:35:13 yesterday) so its five minutes late.

(PS: Don't think I'm making the numbers up as our weekly usage last week was nearly the same as our monthly usage last month - we've been on holiday)

no export figure (Liberty 100 meter) but i get instantaneous export and daily totals in the bright app ?

The IHD/CAD shows the wrong value for electricity

sunsynk - 16.6

Glow mqtt - 16.649

Octopus Mini - 16.65

Glow IHD - 13.35

also on my Glow there are no values for weekly or monthly elec or gas ? maybe these need time to populate ?

cosmetically - the instant 'speedo' shows

export energy as power now negative number anti clockwise sweep

export cost as power now negative number clockwise sweep

surely this should be cost now negative number anticlockwise sweep

Am i doing something wrong or should i report the data display anomaly ?

It seems that the meter resets at 01.00 on the glow and my old IHD - is this a meter thing or a IHD thing ?

Regards Jeff

I am a PAYG customer and my unit displays the ESME PayG balance ok but it doesn't display the GSME balance only the usage.

Is there a way to get the Gas to display balance instead of usage?

Thanks.

Overall, I am very impressed with the unit, especially the MQTT facility which enables me to see real-time electricity and gas consumption data inside Home Assistant.

There is however, one major issue for me. This is the apparent inability (unless I'm missing something) to show live consumption for Electricity and Gas on the home screen.

I also have a Geo Trio IHD which shows live consumption or cost as the default display.

For me, the current days consumption is of no real use, except for historical context. I want to be able to glance up and see what I am currently using.

I know that I can get the current live electricity or gas by tapping on either of the day's usage figures, but it's just not the same as the instant view that the Geo unit gives me.

Being able to switch between today's usage and live consumption must be a relatively straightforward firmware modification.

However, I now have a Glow IHD, and use local MQTT.

But I still see the same 'gaps' in daily data, and it doesnt reset to zero at the beginning of the day (like the electric).

Why is that ?

I didnt capture the MQTT messages, but where there are gaps, I assume thats because the IHD didnt send a 'daily' value (for example, I see a gap at 3pm (strange time!) in the linked image...

The cumulative gas data is correct...in that it only increases, but surely the firmware codeidentifies the beginning of today as always 00:00:00 (local), cant the firmware set to zero at this time ?

I have installed the Bright apo and have created the Tomato tariff using the custom rates option and this works a treat.

My question is that if there is a way to push these custom rates to the Glow IHD(or any other IHD for that matter)

Using teh peak price all day.

how can i get this to show the actual day/night prices.

So far the only advantage over my EoN one is MQTT data to HomeAssistant, where i can show the data and make up my own day/night prices. Which was not the idea

I want to have the ToU in Glow, works in the APP ok. Then show on the CAD screen

Furthermore, Bright app hasn't had any values from the meter since 00:30 today, which more worrying even. I don't know if the IHD being registered to my account did that.

The IHD is sitting less than a metre away from the comms hub, in the same utility cupbaord

Anyway, I wanted to check if it's possible to see the IHD's firmware version?

I do want to buy a local device that collects the data from my meter over the HAN and sends the data to a local MQTT server. But I don't want that device to send any data to any service outside of my local network (Which I'm happy to block myself if needed), nor do I want to authorise any entity other than my electricity provider to view my energy usage (Mostly because its a proxy for occupancy data for my home)

Does anyone know if this is possible? If I bought the Glow IHD could I set it up/pair it with my HAN without also authorising Hildebrand to get a copy of energy usage data from the DCC. Does the Glow IHD stop functioning if it can't send data to Hildebrand's cloud infra?
