MQTT AutoDiscovery (AD) not working in both HA and Domoticz (DM)

[infoedkok]

Installed the dongle today and integrated it with HA en DM.

First with MQTT. Noticed that the items were sent to homeassistant topic but with an onther "flat"structure then I know of other MQTT devices.

E.g , in MQTT Explorer, I see this:

homeassistant> energy_delivered_tariff1=27727.129

Would expect some other structure for AD? But I'm not a MQTT specialist ;-)

So, might that cause the not working AD in HA and DM ?

Switching to the other integration type (DSMR slimme meter by network in HA; P1 smart meter with LAN interface in DM) activates the AD's.

But I would like to get it working with MQTT.

Please advice.

Hi Ed,

Th flat structure is simple but generates a lot of trafic ... this will be changed in a future versie. V5 of the software. It is possible to turn the json payload on via a hidden setting in the settings.json file : "act-json-mqtt":false

De AD of the dongle will publish a structure with homeassistant topic (try MQTTExplorer to check this).

Best way to integrate with DM is via de port 82 option. see: https://docs.smart-stuff.nl/smart-home-systemen/domoticz-and-dsmr-reader But you did already find it ;-)

The AD mqtt publish is once during connecting with the broker. It is a retained message. Sometimes a reboot or reconnect triggers HA.

Warm regards, Martijn

Hi Martijn, Had to be patient ;-), after a while the MQTT 's showed up in HA and DM. Noticed that "act-json-mqtt":false was already in the setting file. And that indeed creates MQTT / AD topics, e.g topic: homeassistant/sensor/p1-dongle-pro/gas_delivered/config { "uniq_id": "gas_delivered", "dev_cla": "gas", "name": "Gas Delivered", "stat_t": "homeassistant/gas_delivered", "unit_of_meas": "m³", "val_tpl": "{{ value | round(3) }}", "stat_cla": "total_increasing", "dev": { "ids": "31682840581340", "name": "P1meter", "mdl": "P1 Dongle Pro", "mf": "Smartstuff" } }

Some strange behaviour in DM (not in HA!): the gas MQTT message causes the creation of a "RFXMeter" -type and "RFXMeter counter" subtype. That type parses data in kWh and not in the "unit_of_meas": "m³" as specified in the MQTT. I was expecting type "P1SmartMeter" subtype "Gas".

But that's DM-stuff, your dongle works like a charm , thanks a lot!

Hi Ed, good to hear that everything is working well :-) Thanks for your feedback!
