Hello,

 

I use an shelly blu H&T on an shelly plus (blu gateway function).

Mqtt on the shelly plus works, but , also with script from GitHub or others, it is not possible to get the temperature and humidity into mqtt.

Battery Status and mac is possible.

 

Has anyone make it work?

 

An college does it with the blu gateway usb dongle, with it, it works.

 

I use following script:

 

/**
 * This script uses the BLE scan functionality in scripting
 * Selects Shelly BLU DoorWindow from the aired advertisements, decodes
 * the service data payload and transfert it to an MQTT broker
 */

// Shelly BLU devices:
// SBBT - Shelly BLU Button
// SBDW - Shelly BLU DoorWindow

// sample Shelly DW service_data payload
// 0x40 0x00 0x4E 0x01 0x64 0x05 0x00 0x00 0x00 0x2D 0x01 0x3F 0x00 0x00

// First byte: BTHome device info, 0x40 - no encryption, BTHome v.2
// bit 0: “Encryption flag”
// bit 1-4: “Reserved for future use”
// bit 5-7: “BTHome Version”

// AD 0: PID, 0x00
// Value: 0x4E

// AD 1: Battery, 0x01
// Value, 100%

// AD 2: Illuminance, 0x05
// Value: 0

// AD 3: Window, 0x2D
// Value: true, open

// AD 4: Rotation, 0x3F
// Value: 0

what do these smilys in the script stand for?

Good morning,

I have the same problem. Did you find a solution?

For my part I use a Shelly Blu Gateway key to run this script and retrieve data from a Shelly BLU H&T temperature sensor, and then recover them in mqtt.

The mqtt works because I get a message on my broker saying that the script has crashed.

The script starts well...it monitors the appearance of the Blu material.

It is when you press the temperature sensor button that the script crash with same error, so there is communication between the gateway and the temperature sensor.
I can't find the error in the script, but I'm not an expert either.

Thank

I was able to reproduce the error. Invalid characters creep in when you copy the script from the forum. @kkoeniger @Athis

Hopefully this is an executable version: 

/**

//Shelly device types ["SBBT", "SBDW","SBDW","SBMO","SBHT"];
let BLE_DESCR = ["Ytterdörr hall", "Dörr veranda"]; // declare descriptive name for each device. Just for easier mapping of mac adresses
let ALLOWEDMACS = ["00:00:00:00:00:00","00:00:00:00:00:00"]; // declare device macs
let DEVICETYPES = ["SBDW","SBBT"]; // need to declare device type
