Smart meter (Belgium)

Hello!

This Friday, my network manager came to install a smart meter at the house.

Yep, in Belgium, mechanical meters are still very, very common (electric).

To tell you, this one was supposed to be installed in 2029 but since the mechanical one was defective, I jumped ahead of the others!

Anyway. The result is that I want to integrate the info from this one into Gladys. Unfortunately, this device doesn’t exist as such.

I managed to extract the data and send it to Gladys via MQTT over WiFi (very easy with a telephone cable and a Wemos D1 mIni, I’ll make a tutorial) but I’m struggling with the categories.

If I take the device called “Téléinformations”, I find some of the categories but they don’t seem to have units:

Also, I must admit I don’t understand all the available terms…

Here is the information transmitted by my meter:

(it is also possible to obtain gas and water info but not in my case)

Maybe we should create a new device and its features?

Hi @GBoulvin :slight_smile:

Great, you’re catching up with us on this topic :joy:

The « Teleinformation (Téléinformation) » device is really specific to the Lixee TIC normally, and normally it’s the Zigbee2mqtt integration that creates these features with the correct units :stuck_out_tongue:

In your case, in my opinion if the only thing that interests you is monitoring your electricity consumption, you should use the « Energy sensor / index » feature:

For these features:

If the value is not an index (if it’s just a kWh value that resets at each reading), you can use the « Energy sensor / Energy » feature.

Then, you’ll have to wait for this development:

Which will allow doing the calculation « Index → 30-minute consumption in kWh → Consumption in euros »

Looks pretty good!

Can’t wait for the dedicated dashboard! :wink:

However, I don’t understand why I have rounding for phase 1 but not phase 3. The data are formatted identically though (they are floats). Any idea?

That doesn’t look too bad!

Yes, same for injection!

It’s a Python script on the Wemos that retrieves the info and then publishes it to MQTT. What I don’t understand is that the data and their processing are the same (with three decimals). It’s Gladys that rounds one and not the other… It’s not a big deal, I’ll look into it :thinking:

I noticed something that might be worth improving in Gladys!

Values are rounded when the page is refreshed, not when they arrive while the page is already open (am I making myself clear?).

The value was rounded (and not the other one) because it was frozen (so not updated).

Thanks for your feedback @GBoulvin!

I’ve created an issue:
