Voor mijn Nederlandse mede-enthousiastelingen: ik heb een flow gemaakt om de zonwering omhoog te doen als er regen wordt verwacht.
For my fellow Dutch enthusiasts: I made a flow to open my awnings when rain is expected.
complete flow incl. de zonwering bediening:
Buienradar heeft een speciale mogelijkheid die ze "widgets" noemen. Als je deze opvraagt krijg je deze tabel:
Buienradar has a special feature which they call 'widgets'. When called it gives you this table:
This is geweldig! Het geeft me het inzicht met een 5 minuten interval wanneer regen wordt verwacht en de hoeveelheid!
This is awesome! It gives me the insight with a 5 min. interval when rain is expected and how much!
I continue in Dutch as this is only useful in The Netherlands:
De Buienradar widget:
De flow is nu ingericht om te handelen als er over 1 uur regen wordt verwacht maar dat kan je zelf aanpassen in de functie RAIN EXPECTED?
je wijzigt hiervoor msg.payload[12] in een ander getal.
'0' = nu,
'01'=nu+5min.
'12'=nu+60minuten etc etc.
zie tabel hierboven.
Uitleg van hun website:
Buienradar widget
(1.0) Neerslagdata op basis van coördinaten
Op basis van de door u gewenste coördinaten (latitude en longitude) kunt u de neerslag
tot twee uur vooruit ophalen in tekstvorm. De data wordt iedere 5 minuten geüpdatet.
Op deze pagina kunt u de neerslag in tekst vinden.
De waarde 0 geeft geen neerslag aan (droog),
de waarde 255 geeft zware neerslag aan.
Gebruik de volgende formule voor het omrekenen naar de
neerslagintensiteit in de eenheid millimeter per uur (mm/u):
Neerslagintensiteit = 10^((waarde-109)/32)
Ter controle: een waarde van 77 is gelijk aan een neerslagintensiteit van 0,1 mm/u.

Many thanks to user Eicid from the Node-Red forum who helped me parse the data from Buienradar.
