DSMR binding suitable for Belgium Smart Meters

Add-ons Bindings
82

I found out about the update rate after my post, the log shows it sends data every seconds.
And will check in advanced thank you!

83

It is available in 4.2.0-SNAPSHOT but still needs some fixing. (the labels in the UI are wrong)

84

Are you referring to the Actual demand/capacity tariff or to the water usage? As for the last one nothing has been added, afaik

85

I would also be interested in obtaining the “Maximum demand – Active energyimport of the last 13 months”
(see e-MUCS P1 V1.7.1)

I can read it via the cu -l /dev/ttyUSB command, but an integration in the DSMR binding would be better.

How or where can we submit an enhancement request?

86

I might give it a try in the future to add it. Since I have the binding installed, I can now see the added value of this channel.
Thanks for opening the issue.

Hello all,
Anyone has tried to connect two cables on the P1 port ?
What did you use as a “splitter” ?

Hi Lamazze,

Maybe this link can help:

Slimme meter via ESP8266 (incl. printontwerp en code) - Duurzame energie en installaties - GoT (tweakers.net)

Good luck!

I bought a 6P4C RJ11 Male to Double RJ11 (7EUR) on a famous American website that sells from a to z and it works perfectly.

Thx for the info!

Does anyone have experience with a device by Smart Gateways? Apparently, there’s one 'for ESPHome, but of course they claim the one with their firmware is better (e.g. at suppressing abnormal readings).

A few years ago, someone wrote a guide on how to use them with openHAB (with MQTT). Not that that guide is anything spectacular, but at least someone uses it with openHAB :wink:

92

@wars, did you get this to work?

93

yes, I had it working via the binding, but I only use it as a backup. My SmartGateway is used as primary device via mqtt.

UID: dsmr:dsmrBridge:xxxxxxxx
label: Smart Meter
thingTypeUID: dsmr:dsmrBridge
configuration:
receivedTimeout: 30
serialPort: rfc2217://192.168.x.x:23
94

And did you buy the ‘extended’ version, or the ESPHome one (see a few posts higher)?

95

Anyone managed to read the water consumption out of the meter?

I had Pidpa this morning to connect their water meter to the electricity meter but it is unclear to me how this works.

96

No one is getting the water meter data?

97

A friend of mine has got his water data import into openHAB working, with this: Maak je Kamstrup Multical en FlowIQ meter slim - SmartGateways.nl

I don’t know his meter type though. (He lives in Antwerp.)

98

Thanks but seems it is used for different type meters.

If I try the cu -l /dev/ttyUSB0 I can see the values on the terminal (in bold below)

0-1:24.1.0(007)
0-1:96.1.1(xxxx)
0-1:96.1.2(2D2D2D2D2D2D2D2D2D2D2D2D2D2D2D2D2D2D)
0-1:24.2.1(xxxx)(00029.535*m3)

99

If you enable debug logging you might see if openHAB reads the water value at all. In that case you could try adding the watermeter m3_v4 manually via a .things file.

Yes, I can see the water usage in the log:

Object(type:EMETER_EQUIPMENT_IDENTIFIER, cosemValues:{=xxx}), Cosem Object(type:M3METER_VALUE, cosemValues:{=29.585 ㎥, timestamp=2025-09-23T17:12:00.000+0200})]

I will give a try adding the meter manually in the next few days

101

I can confirm this works, same for m3_v5_0.

I note that the values are updated every 5 minutes, and I see above there was related request to increase the refresh rate.

Can that be made as a optional parameter that the user can control?

I see the meter is bursting the data every second (if not faster) so it would be interesting in some cases to get the data to OH faster.
