Repeat with port 9001 to verify websockets are open. Run this command sudo netstat -tulpn | grep 1883 and you should see port 1883 open. Save your file and run mosquitto with mosquitto -c /etc/mosquitto/nf and with another SSH client, log into your server and check that the MQTT ports are open. Make sure there are no spaces after any word at the end of the line. Mosquitto is VERY PICKY – if you have a space in the wrong place, it will send an error. Run sudo nano /etc/mosquitto/acl and enter in: Next is to create an MQTT ACL (access control list) so that anonymous users are read only, but the weewx system can read and write to the weather topic. Sudo mosquitto_passwd -c /etc/mosquitto/passwd All other users who connect to the broker are considered anonymous and can only subscribe. For my sake I only have 1 user who can publish. You can get super granular here where certain usernames can publish to certain topics only.
#CONFIGURING MQTT SERVER MOSQUITTO ON WINDOWS PASSWORD#
I locked down my broker so that only those clients who know the password can publish to a topic. Restart Mosquitto with sudo service mosquitto restart and you should now have a working MQTT server on port 1883 and websockets on port 9001! Create a user and access control Make sure you have no empty spaces at the end of those lines or Mosquitto may give you an error.
#CONFIGURING MQTT SERVER MOSQUITTO ON WINDOWS INSTALL#
Best yet, if you use this link you get $10 credit for free!įirst install Mosquitto, which is the name of the MQTT software. You can start your DigitalOcean Ubuntu server for as low as $5/mo and be online in 1 minute. You can run MQTT on a Raspberry Pi, but I recommend running MQTT on a cloud server because it’s always available, fast and easy. This tutorial was created in 2018 using Ubuntu 18.04, so some things may be different after I write this or if you use another operating system.
#CONFIGURING MQTT SERVER MOSQUITTO ON WINDOWS FREE#
Some free ones will handle the frequent data, but offer no uptime reliability, so I decided to install my own broker. I have weewx configured to publish weather loop data to the topic weather/weewx/loop, and my website is configured to subscribe on that topic.ĭue to the high nature that weewx publishes weather data (currently my loop is at 2.5 seconds), I couldn’t use a free MQTT broker (or server), and I didn’t want to pay for access to one.
#CONFIGURING MQTT SERVER MOSQUITTO ON WINDOWS ARCHIVE#
Then you could have weather/weewx/archive for archive data, weather/rain_bucket/current if you had a rain bucket that can talk MQTT. This could mean it’s the weather parent category, the weewx software, and the loop function. For example a topic could be weather/weewx/loop. Topic names are arbitrary, but they should make sense. The device that needs to send data would publish to a topic, and the device that needs to receive that data would subscribe to that topic. It even works great for Arduino or NodeMCU temperature sensors around the house. Initially designed as a lightweight publish/subscribe method useful for those devices in remote locations with limited internet connectivity. If you’re not familiar with MQTT, it’s a machine-to-machine internet of things (IoT) communication protocol. Visitors on my website auto-subscribe to the MQTT topic through websockets and JavaScript updates the data on the webpage within milliseconds.
#CONFIGURING MQTT SERVER MOSQUITTO ON WINDOWS UPDATE#
The result was a true real time auto updating website with no delay! Every time my weather station sends an update from the backyard (every 2.5 seconds), that data is immediately read by weewx which archives the data, runs some QC checks on it for accuracy, then publishes it to MQTT. I knew it was time for a website upgrade! That’s when I saw an MQTT extension available for weewx. It was great to be able to get data from tiny Arduino sensors around the house – but I knew I could do more with it. 10 seconds was far too slow for my liking!Įarlier this year (2018) I started using Home Assistant for home automation (goodbye old unreliable cloud-based automation!) and they opened me up to MQTT. This website, in conjunction with weewx, allowed me to have a website which updated itself every 10 seconds. I wrote this MQTT tutorial to help me out in the future, but hopefully it helps someone else along the way!įor the last few years I’ve been running a custom weather website.
