I am struggling with the following: I am able to receive messages from a MQTT Topic. The message is for example: {“state”:1} In no way I can use this result in a logic part to make a decision. I think that I have to create a script to pars the message. Is there a way and how to get as result afte…

[image] robertklep: const [ full, topic, message ] = args[0].match(/(\S+)\s+(.*)/) Sorry you’r right. I forgot the ‘Full’ part. But finally it works as expected. :sweat_smile: if (args[0] == undefined) { console.log (‘Missing argument’) return false; } let bl = await Homey.apps.getApp({ …

Doesn’t the MQTT Client app provide the topic in a token that you can pass as second argument (args[1]) to your script? Then you can extract the number from the topic name.

[image] RobvandeGoor: opensprinkler/station/7 This is wat I receive as Topic message: opensprinkler/station/7. I only need the last digit. This text does not look the same as the Topic message: {“state”:1}.

[image] RobvandeGoor: opensprinkler/station/7. I only need the last digit. Number(topic.match(/\d+$/)[0])

[image] robertklep: Number(topic.match(/\d+$/)[0]) Do you think 2 labels in 1 script will work? Or should I make 2 scripts? One per label? [Script MQTT]

Yes, I think you can use two labels for one script. The first is accessible as args[0], the second as args[1] (etc…). I would put it all in one script :slight_smile:

I have tested a lot but when the Topic information is like: opensprinkler/station/1, there is no way to get it into a var / script.

Can you receive the topic name in your script? Obviously, instead of using topic in your script, use args[1] if you pass it as second argument: const name = args[1].match(/\d+$/)[0]

I do get all information visible in the script. When I add two arguments in the flow card, the script reads it as one argument. [image] Is there a way to split this?

Oh right, I thought that Homeyscript also had a card that would accept multiple arguments, but apparently it only has a card that accepts one argument. You can split them like this: const [ full, topic, message ] = args[0].match(/(\S+)\s+(.*)/) But you need to switch the tokens in the flow card a…

[image] robertklep: Number(topic.match(/\d+$/)[0]) I got the topic in a var. This problem has been solved. But I created a new one. the MQTT ‘message’ is the total of the message + topic. See used script below and result: if (args[0] == undefined) { console.log (‘Missing argument’) return…
