help return JSON.parse(message) with dot (OBIS Codes) #616

Closed JustAnotherIssue closed 1 year ago

Hey there, My smart power meter exposes OBIS Codes a MQTT middleware. But I got stuck in terms of parsing them in the mqttthing homebridge plugin. Please help me, thanks !!

The issue is about the dots e.g. 1.7.0 in the attributes object.

topic: SHRDZM/serial/sensor response: { "timestamp":"2023-04-15T18:53:55", "32.7.0":"229.90", "52.7.0":"227.60", "72.7.0":"232.60", "31.7.0":"0.68", "51.7.0":"1.31", "71.7.0":"2.12", "1.7.0":"840", this is the attribute/value I need**** "2.7.0":"0", "1.8.0":"749864", "2.8.0":"0", "3.8.0":"309", "4.8.0":"226048", "16.7.0":"840", "uptime":"0000:01:54:05" }

with trying "apply": "return JSON.parse(message).'1.7.0';" I receive an error, "Exception while creating services: SyntaxError: Unexpected string" also with every other tried characters.

Could you help with a clue?

THX!!

JSON.parse(message)['1.7.0'] might do it.
