Domoticz

Posted: **Tuesday 07 August 2018 18:11**

Hey Folks,

For some reason sending battery level to a switch or selector switch in Domoticz via MQTT does not work.

In the below example (link) I am able to control the device but the battery level is simply ignored.

viewtopic.php?f=68&t=23607&start=20#p188171

I am sending it as: msg.payload.Battery

Any help would be appreciated, with Zigbee2MQTT it will be necessary for many devices to have battery levels via MQTT.

Cheers

Anyone?

I've spent about 5 hours trying to get a battery level entered into a device via MQTT without success, it IS possible with JSON.

Seems to me MQTT is lagging behind the JSON interface.

Replied to your github post, but I am pretty sure the "switchlight" mqtt command doesn't interpret the battery variable and you need to change it to "udevice" command as shown in my answer in github.

Problem solved thanks to jvdz example.

What to send via MQTT to Domoticz (in this case to a selector switch).

Code: Select all

msg.payload.idx = 1213 ;
msg.payload.nvalue = 2 ;
msg.payload.level = level;
msg.payload.svalue = level.toString();
msg.payload.Battery = batt;

Tested example in Node-Red for Xiaomi WXKG01LM Button

Code: Select all

Selector switch levels:
10 single
20 double
30 long

Tnx.

It works for me too now.
It's strange that "Battery" seems to be case-sensitive, everything else is lowercase.

Many thanks
For me I needed to switch a leakage sensor On/Off

Spoiler: show

Code: Select all

var level = 0;   // Defaults
var nvalue = 0;  // Defaults
// Prepare Update Domoticz 
if ( leak  === 1 ) { level = 100; nvalue = 1 ;}

msg.payload = {};
msg.payload.idx =  idx;
msg.payload.nvalue = nvalue;
msg.payload.Battery = batt;
msg.payload.level = level;
msg.payload.svalue = level.toString();
if (typeof rssi !== 'undefined' && rssi !== null){
    rssi = Math.round(rssi / 12);
    if (rssi > 12) {
        rssi = 12;
    }
}   
msg.payload.RSSI = rssi;
