Hello coders

I uploaded OpenMQTTGateway with ZgatewayBT.

When I open serial monitor I saw only this:

Can you help me ?

You need to give us more details, version of omg, revision of esp32 env, board…
Did you followed exactly the ble wiki ?

I was try your manual ( https://github.com/1technophile/OpenMQTTGateway/wiki/Module-Overview-ESP32 ) step by step and my uploaded sketch works good :slight_smile:

But I have problem with HASSIO dashboard…

In my serial monitor I have :

home/OpenMQTTGateway/BTtoMQTT/4C65A8D9709B
{“id”:“4c:65:a8:d9:70:9b”,“name”:“MJ_HT_V1”,“rssi”:-65,“distance”:2.009448,“servicedata”:“5020aa01c09b70d9a8654c0d1004f700bd01”,“servicedatauuid”:“0000fe95-0000-1000-8000-00805f9b34fb”}

but in my dashboard I have uknown value …

my configuration code:

  • platform: mqtt
    name: “Mijia Teplomer”
    state_topic: “home/OpenMQTTGateway/BTtoMQTT/4C65A8D9709B”
    unit_of_measurement: “°C”
    value_template: ‘{{ value | round(2) }}’

  • platform: mqtt
    name: “Mijia Teplomer”
    state_topic: “home/OpenMQTTGateway/BTtoMQTT/4C65A8D9709B/tem”
    unit_of_measurement: “°C”
    value_template: ‘{{ value | round(2) }}’

Where I can find correct config.code pls ? Thanks

The issue is that you are using a beta version with the documentation related to v0.8.
You should use the v0.8 while the v0.9 is not released and the doc updated.

You have right :slight_smile:

I was upload v08 sketch and then change HA config to this:

  • platform: mqtt
    name: “Mijia Teplomer”
    state_topic: “home/OpenMQTTGateway/BTtoMQTT/4C65A8D9709B/tem”
    unit_of_measurement: “°C”
    value_template: ‘{{ value | round(2) }}’

and wait few minutes and vuala :slight_smile: value change from uknown to correct value from mijia sensor :slight_smile:

It was a fight :slight_smile: thanks a lot for your help
