Guys, Trying to make some decisions on weather data that i am parsing and storing - it looks like this when stored [image] I am wanting to use a switch node to look for permutations with the word sunny in the description. There does not seem to be a concise list of these on the website (typical …

I don't think there is an issue with the switch property expression -- the problem is that your regex does not match the string stored in your global context... Is there a reason you are using such a complex regex? Notice how the context var ends with a period . ? But your regex states that the v…

The original source data does not contain anything else useful ? like cloud coverage or something ?

You can try something like this ^(?!(partly|mostly))(.*)?(sun|sunny)$ Test Flow: [{"id":"2867986b801a84ef","type":"inject","z":"54efb553244c241f","name":"","props":[{"p":"payload"},{"p":"topic","vt":"str"}],"repeat":"","crontab":"","once":false,"onceDelay":0.1,"topic":"","payload":"Sunny","payload…

[image] craigcurtin: do you know if there is a list of what is acceptable though in the switch node regex field ? You can check out the Javascript regex documentation - if you really want to go down that rabbit hole... just keep in mind that in Javascript the expressions are inside slashes, w…

I assume that the i in \sun\i is to ignore the case. So both sunny & SUNNY, etc would be 'true'.

[image] bakman2: "occasional sun" could be the equivalent of "shower or two", doesn't sound very reliable. Yep but they are the most accurate 12 hours - 24 hours out - so i can use this in the low solar months to enable precharging of my batteries overnight to enable peak shaving the next day…

[image] shrickus: Put that expression in the Property field, and add output ports for the boolean values: [image] Thanks thats given me a good head start - and probably easier to decipher in a years time than the regex i would end up with Craig

@shrickus OK what you had sort of works for me - but what i wanted to do was reference the property as a Global Context object - the reason being that i could then reference multiple values in the tests such as Sun (to match all the sun conditions), Cloud to match all the cloud conditions etc Using…
