You can calculate the export from the Glow IHD stuff. I'm doing that with my simple Arduino sketch that displays the current "meterReading/out/elec" from my Glowmarkt IHD on a simple LED strip. I'll put the latest code on github at https:/…
-
Have you asked Glowmarkt's tech support? Have you provided the serial from your IHD (as supplied by your electricity company)?
-
Send an email to Glowmarkt
-
If you know the tariff then the amount can be calculated using simple maths.
-
The Glowmarkt systems are all read-only. The read smart meter data and display it (or publish on local MQTT) and nothing more. If the smart meter is 'off' (which is unlikely) then the Glowmarkt IHD would get nothing.
-
Those fields are there for future development.
-
You can chose JSON or nothing.
-
It should happen automatically (as long as you have a stable internet connection).
-
Sorry I was wrong. It is a Zulu timestamp so should be in the format yyyy-dd-mmThh:mm:ssZ.
-
The timestamp is local (not Zulu) anyway.
-
I've documented all of the JSON that comes back from the MQTT API in https://github.com/DougieLawson/glowmarkt/blob/main/mosq.c I take that JSON and decode everything in https://github.com/DougieLawson/glowmarkt/blob/main/mosqJSON.c I decode just…

@billytkid To convert cubic metres to kilowatts you need to know the calorific value of the supplied gas (which can vary). Multiply by the volume correction factor (1.02264). Multiply by calorific value (~40.0). Divide by kWh conversion factor (3.6…

MQTT isn't working for me either right now.

Have Glow fallen foul of the five Sundays in October (DST ends on the last Sunday) this year? @JaneAtGlow @clivee
-
Try this mosquitto_sub -p 8883 --capath /etc/ssl/certs -h glowmqtt.energyhive.com -u "someone@gmail.com" -P somethingsecret -t "SMART/HILD/CAFEDEADBEEF" No protocol needed on the host name.
-
Are you using the latest versions of the Mosquitto client programs? http://mosquitto.org/download/ ii libmosquitto-dev:armhf 2.0.12-0mosquitto1~buster1 armhf MQTT version 3.1/3.1.1/5.0 client library, development files ii libmosquitto1:…

It's working for me right now. Thank you.
-
I've not recorded a gas reading since 2021-10-12 15:51:14. @clivee
-
@clivee @JaneatGlow need to look at this. The MQTT feed is dead again.
-
You're missing the TLS support and the port number is wrong. --capath /etc/ssl/certs -p 8883
-
Send an email to support@glowmarkt.com with your IHD serial number to get Clive and/or Jane to take a look at this for you.
-
mosquitto_sub -p 8883 --capath /etc/ssl/certs -h glowmqtt.energyhive.com -u "example@gmail.com" -P superSecretPassword -t "SMART/HILD/DEADBEEFCAFE" I use --capath rather than --cafile as that gets mosquitto_sub to search for th…
-
@clivee thanks for confirming I wasn't going mad. I have a process that's always reading my MQTT data.
-
@clivee @janeatglow my IHD still isn't showing the Octopus Go tariff, what do I do next?
-
To convert the m^3 value for gas consumption to kWh, BTU or joules you need to know the calorific value from your gas supplier. https://www.nationalgrid.com/uk/gas-transmission/data-and-operations/calorific-value-cv

What happens if you change the topic from SMART/DCAD/BCDDC2C6A780 to SMART/+/BCDDC2C6A780 (using the MQTT topic wild card support)?
-
I do have the BrightApp and I am using the MQTT API (which is very good and reliable with the latest firmware on my IHD). I was just looking to tinker with the stuff on the Glowmarkt website, but it's to much of a pain to get it working.
-
https://glowmarkt.com/register.html needs improvement. I've been through that page more than once yet it treats me as a "new user" every time I re-visit. Store a token in a cookie and don't ask all the MPAN etc. questions all over again (u…
-
@clivee It worked perfectly for me just using `mosquitto_sub` so I've built that into all of my API code. Here's a simple example. #include <stdio.h> #include <stdint.h> #include <string.h> #include <unistd.h> #include <m…

Then you'll need to ask @JaneatGlow or @clivee to check your credentials and reset them.
