Some weeks ago I changed from build-in Zwave to Zwave via MQTT. I had to delete several nodes and re-create them. It finally worked. However, some deleted Nodes have still Devices in the Device-list. When I delete these Devices, they re-appear after a restart of Domoticz or later at some other time ...

@ niki_lauda: What do you want to know? Domoticz is running on Raspberry Pi. You have to install sqlite to be able to access the database. When you want to give sql instructions from LUA, you also have to install 'luasql'. sudo apt-get install sqlite3 sudo apt-get install lua-sql-sqlite3 sudo reboot ...

It appears the computer had to be restarted.
After restart the problem disappeared.

EDIT: It appears the computer had to be restarted. After restart the problem disappeared. I want to modify the Domoticz database from a LUA script (yes, I know all the risks). I installed a library (lua-sql-sqlite3) to access sqlite3 directly from LUA (sudo apt-get install lua-sql-sqlite3). When I ...

There are wall-switches that react on sound to switch on lights. You could place such a device near the fire alarm. Tune the device that it only switches on when the sound is very loud. Instead of a light you connect a z-wave device that sends an On signal when powered on. In Domoticz you will have ...

I found the same issue as svenker. However, the explanation of dannyblue also makes some sense. Although it would have been much better to call it PreviousUpdate. If you have a Domoticz master/slave installation, then you will see the same device twice. In LUA this exactly the same device will show ...

As you surely have read the documentation says that the AWMT-230 is not for led lights.

I use an alternative for monitoring if power is On:

It does the trick of the inverted state.

When you have flashed the ESP8266, connect it to a external power-suply (not a computer) for the next steps.
I found that this makes the process with the setup work.

Use a KAKU keyfob I tried to avoid solutions that are based on sending more 433 Mhz Signals. This would polute the 433 Mhz-ether even more and so disturbing other 433 Mhz signals. with quite a big storage capacitor I had a prototype where a capacitor (2 x 4700 micro Fahrad) would keep the Wemos D1 ...

You ask after power-supply. I have several ESP8266 devices, most of them Wemos D1. I power them with a Hi-Link PCB Voeding (5 Euro). See: https://www.tinytronics.nl/shop/nl/voedingen/5v/hi-link-pcb-voeding-5vdc-0.6a-hlk-pm01 I use these power supplies (or their 1 Amp version) also for Arduino ...

If you want a quick(er) response that the device is On or Off, you should leave the Wemos D1 powered on all the time and use a sensor to see if the Device were are monitoring is On or Off. As sensor a light-sensitive resistor will do. You can build your own Opto-coupler by using a light that is put ...

When the power outlet is powered down, the Wemos D1 will also power down and stop running. This is something we can detect with software. When the Wemos D1 is off, the Device that is monitored is also off. That's the idea. Create a LUA Event in Domoticz. Make it a Time-driven event. This will check ...

Detecting the 'On' state is easy as can be. You plug your Wemos D1 in the same power outlet as the device you want to monitor. When this power outlet is switched on, the Wemos D1 will also power on and boot. It will then send the boot-state of the dummy-device to your controller. Since the dummy ...

Moderator - Please delete this reply, it was double.

Build the hardware For the detection device I used: - 'Wemos D1 Mini V2-ESP8266-12F - CH340 - 'Hi-Link PCB power-supply - 5VDC, 0.6A - HLK-PM01' - Housing - Line cord You solder the line cord to the power-supply and the plus and minus to the Wemos D1. WemosD1AndPowerSupply.jpg Put it in the housing ...

When the connection to ESPEasy on you Wemos D1 was succesful, you will see a welcome screen. Click on 'Proceed to Main Config'. Then configure several menu-tabs: ESPEasyConfig.png Menu --> Config - Choose a unique Unit Name for your device and a Unit Number. - If you have multiple ESP8266 devices in ...

As 'operating system' I choose 'ESPEasy Version 2.10': https://www.letscontrolit.com/wiki/index.php/Main_Page Install the setup-program on your computer. Then you start the tool FlashESP8266.exe and choose the version. I used 'ESPEasy_v2.0.0-dev10_normal_4096'. Of course, when you read this, there ...

Have you ever wanted to detect if your Domoticz driven switch, light or power outlet was powered On or Off? Just to be sure? Or to know it at all? Of course some equipment provides a return signal to indicate if a device is on, but 433 Mhz gear, like KaKu (Klik Aan Klik Uit) / CoCo (Click On Click ...

I started this project for my personal needs. I was surprised about the outcome. It works and - actually - quite good. The range of the receiver and transmitter are at least as good as my RfxTrx433E devices. So, I thought to share it with you. However, this is not a project that I will develop ...

The 'Main' program to connect Domoticz and Arduino on the Raspberry Pi is a Python program. I called it ArdToDom. This is Python program ArdToDom: #!/usr/bin/python3.4 # /home/pi/python_programs/ArdToDom.py # ArdToDom = Arduino To Domoticz # open: lxterminal -e "/home/pi/python_programs/ArdToDom.py ...
