Hi any idea how to change the user name and password, trying to connect to Hassio mqtt and not allowing it, When publishing to Hassio the mqtt broker uses a username and password,how can i alter it to my user name and password, exactly what i was looking for, unable to use it, as Hassio needs a password and user name, big pity,:( as i used mqtt explorer and it works like a dream, would you beadle to add that into the settings page? It may also be too far from the rest of your equipment to be practical, as it was in my case. I Create my own project using Water meter sensor using arduino uno + LoRa Shield Dragino my sketh code using this code: #include #include int count=0; int device_id=6667; // ID of this End node /* Liquid flow rate sensor -DIYhacking.com Arvind Sanjeev Measure the liquid/water flow rate using this code. If you have the skill, you could save a lot of money doing it yourself but it is definitely not a project for amateur plumbers! Glad I read the comments. Don’t get a cheap meter designed for garden hoses and install on your water main. MQTT-based water meter configuration for Home Assistant - configuration.yaml. In addition to flow rate, I included some binary sensors for sustained flow and high flow as well as daily cost, which can be configured through variables. More research uncovered a selection of meters in the $150 range that fit the bill. Thanks! Unfortunately that will probably cost more than the meter itself. Here are the main things to look for: Make sure the meter is designed for the size of your incoming water main.

Great post, and exactly what I was looking for help with. | Shopping Australia To use your MQTT sensor in your installation, add the following to your configuration.yaml file: - - parameters according to meter type: - for o,s,e,m,r: serial baud rate eg. This video is unavailable. Configuration. I’ve pretty much settled on Home Assistant as my DIY automation platform. If messages in this state_topic are published with RETAIN flag, the sensor will receive an instant update with last known value. Some are ZWave which integrate easily and others have a simple pulse output you’ll need to interface yourself (see below for more).
