StookAlert

StookAlert (only for the Netherlands)

Note: The old script that was here is not working anymore due to change of API on the website.

DzVents script that gives advice by RIVM when it's suitable to use your wood-burning stove. For more info: https://www.rivm.nl/stookalert

• Create a dummy Alert Sensor, it will appear in the utility tab.
• You can copy and paste this dzVents script with Setup - More Options - Events. Create a new dzvents script with trigger HTTP and paste the contents over the template.
• Modify the script with your province and the idx of the Alert Sensor.

dzVents Script

-- StookAlert. 
-- The stookalert sensor platform queries the RIVM Stookalert API for unfavorable weather conditions or poor air quality. 
-- With a Stookalert, the RIVM calls on people not to burn wood. 
-- This can prevent health problems in people in the area.
