To be used without home automation software

The gateway’s web server displays the water level in real time. This makes it possible to use the gateway even without home automation software. Water level elevations are calculated and displayed in real-time based on the entered maximum elevation and any offset from the sensor.

Home Assistant integration

The Distancemeter WiFi Gateway fully cooperates with Home Assistant. A nice dashboard shows all the data in one view. These include the distance in centimeters from the surface of the water. By entering the total distance from a sensor to the bottom of the tank, Home Asssitant itself calculates how full or empty the tank is and displays it in percentages.

The gateway also sends important diagnostic information to Home Assistant and the firmware can be updated via the dashboard.

MQTT topics

The Distancemeter WiFi Gateway publishes the following MQTT topics:

These topics can be read by Home Assistant, Domoticz or any other package and then displayed in a dashboard. As a result, the possibilities are endless!

Prevention of fluctuations

The gateway measures the distance to the surface at a rate of 10 measurements per second. It occasionally happens that a measurement is slightly off. This is quite normal. To avoid these small fluctuations, the gateway itself calculates the average distance from a number of values. This average distance is transmitted along with the real-time distance via MQTT and the REST API. This ultimately ensures that the home automation software used will reflect the distance stably. Choose which measurement to use.

Configuration

The Distancemeter WiFi Gateway will broadcast a WiFi network when first used. If connected to the “SmartGateways DistanceMeter” ssid, one’s own WiFi network can be selected. Then the mqtt server used and a static ip address can be set, if necessary. Once connected, the gateway sends the consumption to the set mqtt server. If a fixed ip address is required, this can also be specified. An installation guide for Mosquitto MQTT can be found on our support page.

Web server with JSON API

The Distancemeter WiFi Gateway has an internal web server on which all information can be accessed via an API link. The Web server runs on port tcp/82 and can be found based on mDNS via http://connectix_distancemeter.local:82/distancemeter/api/read. The image below shows a screenshot of the contents:

Firmware updates

Development is an ongoing process. As a result, new firmware updates may be released. These updates can be installed automatically. The gateway will automatically check for updates every hour. These can then be installed at the touch of a button.

Gateway version information and available new firmware are also transmitted via MQTT. This allows this information to be displayed on the dashboard you use. The new updates can even be installed through the Home Assistant dashboard without physically being at the gateway!

Support for Domoticz

The gateway can be easily interfaced within Domoticz through the built-in web server with API. The instruction will be available soon.

Support for Homey

The Distancemeter Gateway can be paired via the Smart Gateways App for Homey.
