HarleyK thanks for this info I finally got my Miija Light Sensor working.

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

Firts of all: many thanks for helping me!! 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 ...

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'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 ...

Okay my MQTT looks okay because it stated several data from other sources but not from my POW.
The POW is updated in Domoticz but not in NODE RED / MQTT. What am I missing?

I've Tasmota 8.1 @ Sonoff Pow R2 Module and the Power consumption is displayed in Domoticz and every 5 mins its getting updated. In NODE RED I'm using a MQTT IN and a JSON component. I see all kinds of messages so it seems to me that's working correctly but I don't get any kind of data from my POW ...

I solved it and the solution was here (where it always was but I simply ignored it because I thought python was completely installed .... NOT) https://www.domoticz.com/forum/viewtopic.php?f=28&t=27104&p=207816&hilit=zigbee2mqtt+hardware+type#p207816 "After running: sudo apt-get install python3-dev ...

I've tried it on a another RPi (3B+) but with the same result (nothing showed up hardware type). Could it be a defect on the CC2531 stick? How can I check it

I did both

Yes but it did 't read a solution

I've a flashed CC2531 stick, installed zigbee2mqtt and python plugin on a domoticz@RPi2.
So far so good but I get stuck on the following:
On Domoticz 》hardware I want to select zigbee2mqtt but there's no zigbee type to selected.

What am I doing wrong?

I thought I read that the batterylevel is shown in Domoticz but after connecting the smoke detectors (SA-33) the battery level is not set (see attachments. Is this possible and if so how to achieve this?

Hello,

Is it possible to connect the Alecto SA-66 smoke detector with a Rfxcom 433 XL / Domoticz? And if so, how can I configure them?

Greetings
Peter

Hi great work!!!

I'm thinking to make one for myself but I'm curious: is it still works nicely? If you where me would you do something differently?

its true that in some cases the 5v of the Rpi is not sufficient. a different power supply might help.
when you use the battery, does domoticz get a signal?

Yes domoticz get the signal. I now ordered a NPN which is more suitable for 5V

I've a RPi with an NPN sensor (LJ12A3-4-Z/BX Nabijheids sensor N/O NPN 4mm) and connected (Black > pin 40, Brown > 2, Blue > 39). I'm using the python code from markiemark (thanks !). When I hold the NPN against a metal item the LED lights up and when removing the metal de LED is off so NPN seems to ...
