radioactivity_hu's Introduction

Home Assistant custom integration for Radioactivity data for Hungary

This custom component integrates radioactivity information provided by Disaster Recovery Directorate (Katasztrófavédelem).

The state of the sensor will be the level of the environmental radioactivity. Thresholds are defined on the bottom of the page Háttérsugárzás - Aktuális adatsor

Installation

The easiest way to install it is through HACS (Home Assistant Community Store), search for Radioactivity Hungary in the Integrations.

Configuration:

Define sensor with the following configuration parameters:

Name	Optional	`Default`	Description
name	Y	`radioactivity_hu`	name of the sensor
station	Y	``	name of the measuring station (see below)

Measuring station name should match the 'Állomás' specified at Háttérsugárzás - Aktuális adatsor. When not set the component will scan all active stations with measurement data not older than two days and the state of the sensor will be the highest level of measurement from this set of stations. The attributes (station, last_measurement_time) will be set as per the station with the highest level of measurement.

Example of radioactivity information:

Examples

          if ( r_val > 500 ) {
            return "red";
          } else if ( r_val > 250 ) {
            return "var(--paper-item-icon-active-color)";
          }
          return "var(--paper-item-icon-color)";

radioactivity_hu's Issues

a station but it doesn't work

Hi! I tried Székesfehérvár as a station but it doesn't work. If "unavailable" is displayed in the filter states line. I tried several other cities, they work.
Thanks!

can't add custom card

reported error in script:

ButtonCardJSTemplateError: TypeError: states['sensor.radioactivity_hu'] is undefined in 'var r_val = states['sensor.radioactivity_hu'].state; if ( r_val > 500 ) { return "red"; } ...'

Filter out inactive stations

The RAD.json has a field active for each station. This field is true only when the station has valid measurement data.

In this moment for example, station ID 103 has the active field set to false:

The station shows invalid meaurement data: the measured value is errorneously 329000 (and moreover, during the night it had a peak of 2.8 million) which means we all would be dead by now :D

This is important for the case when station parameter is not set in the configuration, the errorneous station with extreme values will always be shown as alerting.

Inactive stations are filtered out from the official webpage too (inactive stations are not shown in the list):
