This custom component integrates water quality information provided by Budapest Water Company (FVM - Fővárosi Vízművek).
The state of the sensor will be the number of monitored items above their threshold. Thresholds are defined on the FVM vízminőség, vízkeménység page (see below).
State of a water quality element can be either ok or out of range.
Water hardness value is listed with other monitored elements, while the human readable water hardness string is listed as a standalone attribute.
The easiest way to install it is through HACS (Home Assistant Community Store),
search for Water Quality FVM in the Integrations.
Define sensor with the following configuration parameters:
| Name | Optional | Default |
Description |
|---|---|---|---|
| name | Y | water_quality_fvm |
name of the sensor |
| region | Y | Budapest - I. kerület |
region string (see below) |
| ssl | Y | true |
control SSL verification. This is useful when CA store update with new root/intermediate certificates is problematic. WARNING: setting this to false is a security breach. |
Region should match the location specified at FVM vízminőség, keménység.
Example of water quality information:
platform: water_quality_fvm
region: 'Budapest - XXII. kerület'
