This application is only suitable for Dutch users
This application uses a Node Red solution, which polls an undocumented API of https://www.rivm.nl/stookalert from RIVM and sends its value with MQTT to a virtual Domoticz sensor.

Especially in the winter period it is quite popular to burn wood in your fireplace, pellet stove or use a fire pit.
Sometimes the weather conditions are very bad, like wind still weather or fog, and that will hinder your neighbours, because the smoke lingers.
RIVM maintains a website, where you can see in which province a smoke alert is given. (https://www.rivm.nl/stookalert)
Normally the smoke alert is given at around 12:00 h at noon and is valid for the afternoon and the evening of the day.
This flow checks an undocumented api (at least I could not find it at the RIVM site) hourly and sends a text to a virtual alert sensor.

Usage:
Insert in the Inject node, called "Select Provincie" your preferred province as a string to msg.topic.
In the function node, you have to insert your Domoticz IDX number of the created virtual "Alert" Sensor at line 4.
At line 6 and 7, you can change the texts, you want to see in the virtual "Alert" sensor.
Code: Select all
// Stookalert (only available in The Netherlands)
// Insert Domoticz IDX number of virtual "Alert" sensor below.

var stookalert = "De weersomstandigheden zijn de komende uren ongunstig, zodat het afgeraden wordt om hout te stoken.";
