MQTT: executing 2 commands for switching light

[pedemo]

I'm trying to switch my lights with MQTT but I don't got it to work. Now I'm testing it with mosquitto_pub and the following occurs:
When I try command [1] only: nothing happened
[1] mosquitto_pub -h localhost -m '{"command": "switchlight", "idx": 310, "switchcmd": "Toggle" }' -t 'domoticz/in'

But when I enter command [2] after command [1]: the the light switched on:
[2] mosquitto_pub -h localhost -m '{"command": "getdeviceinfo", "idx": 310 }' -t 'domoticz/in'

what am I missing / doing wrong??

If you have your domoticz MQTT "hardware" configured with Prevent Loop True (the default) the incoming command

Code: Select all

mosquitto_pub -h localhost -m '{"command": "switchlight", "idx": 506, "switchcmd": "Toggle" }' -t domoticz/in

will be executed but will not be echoed to domotiz/out

the incoming request

Code: Select all

mosquitto_pub -h localhost -m '{"command": "getdeviceinfo", "idx": 506 }' -t domoticz/in

will be executed and when listening with

Code: Select all

mosquitto_sub -F "%U - %t - %p" -v -p 1883 -t "#"

you will see

Code: Select all

1598431402.400431855 - domoticz/in - {"command": "getdeviceinfo", "idx": 506 }
1598431402.558232479 - domoticz/out - {
        "Battery" : 255,
        "RSSI" : 12,
        "description" : "",
        "dtype" : "Light/Switch",
        "hwid" : "3",
        "id" : "0001424A",
        "idx" : 506,
        "name" : "MQTT test",
        "nvalue" : 0,
        "stype" : "Switch",
        "svalue1" : "0",
        "switchType" : "On/Off",
        "unit" : 1
}

Okay clear, but the command mosquitto_pub -h localhost -m '{"command": "switchlight", "idx": 310, "switchcmd": "Toggle" }' -t 'domoticz/in' doesn't toggle my light. How can I switch my light?

I'm a newby so forgive any "dumb" questions

I cannot replicate that, My lights do toggle from Off to On and vice-versa with that command.

How is your MQTT configured in domoticz?
What do yo see in the domoticz log when entering that command?
What do see when entering that command when you listen to port 1883 with

Code: Select all

mosquitto_sub -F "%U - %t - %p" -v -p 1883 -t "#"

What is the deviceType / subtype of your device as seen on the device tab in domoticz?

Firts of all: many thanks for helping me!!

* I install it with sudo install mosquitto
* Nothing is shown in the Domoticz log file when entering that command. When I exectue both commands the lights went on but nothing is shown in the log
* When entering command: mosquitto_sub -F "%U - %t - %p" -v -p 1883 -t "#" it stated a bunch of info
i.e.

I don't know where to find it (maybe you can put it here in Dutch because I'm using it in Dutch

[pedemo]

I figured it out by myself. In DOMOTICZ | HARDWARE I edited my MQTT GATEWAY
I set the 'Prevent Loop' from TRUE to FALSE (see attachment) and now it reacts on the first command

If you don't see anything in the log it could mean that the commands are not received by domoticz or that your logging does not show the normal / status log. What is the output of
