I had a few problems to get it right and maybe this post helps others to NOT make so many mistakes than I did I am running the currently latest Dietpi Version 7.3.x Installing MQTT Broker: "Mosquitto" log on to your dietpi via ssh. run: pyhon3 -V result : Python 3.7.x Should be somewhere @ 3.7.x or higher Install software via "dietpi-software" - search for: "pip" - should find package n#130 "influx" - should find package n#74 = InfluxDB "mosquitto" - should find package n#123 Important: I also installed "paho-mqtt" via: sudo pip3 install paho-mqtt # if you forget this step - like I did first - the listener will not publish to the MQTT Broker but still works!! WITHOUT any ERROR message # You will only notice that the when you run listen.py from the command prompt that the line: # "publishing to" will be missing # It took me a while to figure this out Next I changed the "mosquitto.conf" file located in /etc/mosquitto I installed Midnight Commander via dietpi-software and started "mc" from here Then opened "mosquitto.conf" for editing via "Edit F4" and added a line: allow_anonymous true # obviously to allow connection without user & password and changed the listener line to: listener 1833 0.0.0.0 #otherwise mosquitto starts in "local ONLY"mode I then restarted the mosquitto server: systemctrl restart mosquitt.service and checked systemctrl status mosquitto service I then changed directory to: cd /usr/local/bin/ Create a new text file via: touch listen.py - or by any other means Then go to: https://github.com/vinceskahan/weatherflow-udp-listener click on "listen.py" and then on "raw" "ctrl-a" > ctrl-c" - copy I then started "mc" and opened "listen.py" for editing and pasted the content from the above via "shift-ctrl-v" then quit via F10 and save the file. Then I started: python3 /usr/local/bin/listen.py -b 127.0.0.1 -m -d This should produce some output like: rapid_wind => ts = 1624942363 mps = 2.07 dir = 131 publishing to mqtt://127.0.0.1/wf/rapid_wind I then edited the dietpi "custom.sh" file @ /var/lib/dietpi-autostart/ and added the line nohup python3 /usr/local/bin/listen.py -b 127.0.0.1 -m I then run dietpi-config and changed Autostart options to n#14: Custom This should start the listener.py automatically after a reboot. NI then checked that the MQTT Broker "mosquitto" is running and reachable! I use "MQTT Explorer" which is free and available for all major plattforms: Can be found here: http://mqtt-explorer.com/ Install on any machine on your network. When you are connected to your MQTT server you should find the topi "wf" and now all should be good to go and run the QuickApp You might also want to publish to InfluxDB for later use with grafana or so by adding the options to the listen.py command line. for options look at: https://github.com/vinceskahan/weatherflow-udp-listener ....and last but not least again thanks to: vinceskahan for the brilliant "listener" -- THANKS afendikov for providing the QuickApp -- THANKS and Bodyart @ for providing an alternate way of reading out the WeatherFlow data ..and of course anybody else I might have forgotten to mention here. THANK you very much Cheers Jürgen PS: Please report if you spot anything wrong here!

Hi to you all! Maybe you know that I'm a critical HC2 user since 2013. In short, as I mention here I was feeling the Fibaro was holding me back in possibilities, privacy and security. So I started to investigate to get more control over what I think was important to me. I said I would abandon the HC2. The good news, I will not (for now). After extensive testing and trying to find a proper configuration, I found a way to implement the HC2, demanding my needs and wishes concerning: Security Privacy Possibilities Time to spend (re-configuring 200+ devices, 50 scenes and 30 Virtual Devices) The solution I'm implementing is a Raspberry Pi 3 with Node-Red for all communications from the HC2. In short, this means using the HC2 solely as a Z-wave controller and automation gateway. Setup: - The Node-Red will receive commands from the HC2 by an encrypted (https) and password protected connection. At this point it's still one way by sending from the HC2 to Node-Red. - The HC2 is (will be) blocked from internet access. Internet access to the HC2 will be done by VPN. - All other domotica devices are on a separate subnet (VLAN). - All messages (email/push/Telegram) is processed by Node-Red. (disabling all Fibaro 'services'). Example: An alarm is breached: - HC2 will send a message by https to Node-Red. - Node-Red sends IP-Camera snapshots to own email-server, push-account or private Telegram-bot. - Node-Red will check my Ubiquiti manage-switch to check if someone is at home (Mobile phone present in LAN) at will send result to push or Telegram. For sending data to Node-Red a scene is used with content of 5 Global Variable, triggered by one: SC_Nred_VarName (Name variable to send. used as trigger, must be written as last) SC_Nred_VarVal (Value to send) SC_Nred_VarType (not used yet, could be used for sending the type of value, like string, date, time etc.) SC_Nred_VarLog (data for storing data in Node-Red logfiles) SC_Nred_VarPath (path to the Node-Red http-receive-node, default /hc2) The scene code (Beta code 20170526): --[[ %% properties %% events %% globals SC_Nred_VarName --]] -- -- Initialisation of user settings (change if necessary) -- -- Global variables (has to be added manually in HC2 variables panel) local globVarName = 'SC_Nred_VarName'; -- Name of global variable to send (trigger!) local globVarValue = 'SC_Nred_VarVal'; -- Value of global variable to send local globVarType = 'SC_Nred_VarType'; -- Type of global variable to send local globVarLog = 'SC_Nred_VarLog'; -- Logmessage to send local globVarPath = 'SC_Nred_VarPath'; -- Node-Red http-node path to interact with -- Node-Red server connections credentials local nredIp = '192.168.x.x'; -- Node-RED server IP-address local nredPort = 1880; -- Node-Red server port number local nredUser = 'HC2'; -- Node-Red user used to change variables local nredPass = 'XXXXXXXXXXXXXXXX'; -- Node-Red password of used user -- Node-Red server credentials options: true = Enable, false = Disable local nredUseLogin = false; -- TODO!!

Just want to share this example because the possibilities are huge! Greetings, Lambik

The genesis of this post was a desire to try and simplify the third party programs (mainly sonos http api, HA bridge & NUT UPS monitor) that I have running on a few Raspberry PI devices. The Goal - Get them all onto one Pi device, move from SD to USB booting and overall make it easier to manage, especially in the case of a crash (ie have a spare usb stick) I currently don't use NodeRed or MQTT but decided to include them as well to see if I could get them all working on a Pi3 I ended up with the following running on a Pi3 from a Sandisk 16gb Cruzer USB memory stick sonos-http-api - https://github.com/jishi/node-sonos-http-api HA bridge - https://github.com/bwssytems/ha-bridge NUT UPS Server - https://networkupstools.org/ NodeRed - https://nodered.org/ Mosquitto MQTT (broker and client) - https://mosquitto.org/ The results can be accessed at Sonos API - http://192.168.1.240:5005/Livingroom/state HA Bridge - http://192.168.1.240/#!/ NodeRed - http://192.168.1.240:1880/ MQTT pub and sub available at 192.168.1.240 NUT UPS service listener at 192.168.1.240:3493 Preface: The following steps worked for me and I referenced some of web pages I used but not all. I use Windows and I don't know the MAC equivalents. My purpose for posting is to document what I did and hopefully this may help some users get started. It is not meant to be a foolproof guide that will work for all. You may come across some issues I never encountered and your best friend is google for resolving those ...af ===== Installing Raspbian Buster Download the zip from https://www.raspberrypi.org/downloads/ Use an application such as Win32DiskImager and a card reader to burn image onto SD Card (or Flash drive) Before removing the SD card from the Card Reader use File explorer to view the content of the SD Card Place a file called SSH (no file extension) into the root folder of the SD Card. This will allow you SSH into the Pi and use it headless Place SD Card into Pi, connect Ethenet and apply power Use Advanced Port Scanner (PC) or Fing (mobile) to find the IP address of the PI Use Putty to SSH into the PI (enter IP address and port 22) Login into Pi Username - pi password - raspberry You can change the password if you like Booting from SD card and then from the USB Flash Drive If you have a Pi3 you can get your Pi to boot from a Flash Drive/Memory Stick. It is documented below but in summary thisisi what you do Initially burn a standard raspbian image on an SD card. You then boot up the Pi using the SD card and run some commands over SSH. This tells the Pi to boot from USB first the next time Burn a standard raspbian image onto a Flash Drive. Remove the SD card and insert the Flash Drive and power on. It can take 20-30 second to boot and get a SSH connection so be patient. Don't forget to add the SH file (no extension) in the root of both the SD Card and Flash Drive/Memory as described above to enable SSH access from each to the Pi Boot up the PI with the SD card and a standard Raspbian Buster Image SSH in the Pi Enter the following commands (one per line) sudo apt-get update && sudo apt-get upgrade echo program_usb_boot_mode=1 | sudo tee -a /boot/config.txt vcgencmd otp_dump | grep 17: The last command should give a result like 17:3020000a If not then repeat the above steps Power off pi Remove the SD Card and insert the Flash Drive/Memory Stick into one USB port Add power and ethernet and let it boot (It can take up to 30 seconds to boot up) SSH in as normal and confirm you can log in Use an application like WnSCP if you want to get file access to the card/flash drive while it is running on the Pi References: htps://www.raspberrypi.org/documentation/hardware/raspberrypi/bootmodes/msd.md ====== Install NODE.JS & NPM I use Node.js v8 here as there appears to be a conflict between v10 and npm where npm doesn't work correctly.

Hi2Uall! I configured a (working) Raspberry Pi 3 Raspbian with Node-Red and MQTT (see this excellent YouTube video for explanation). Now on working, and learning (a lot) how to implement this. So far it is very useful to connect several IoT services. Did anyone have an idea how to connect the HC2 to an MQTT server?
