- Issue of the topic:
I am receiving data from a Fronius Symo inverter through the Fronius binding in OH3, it’s working fine (as far as I can tell).
The binding reads a lot of data and communicates that back to OH3, including but not limited to the inverter state codes and any error codes. Fronius language is a little confusing here in that error codes do not necessarily indicate an error in the operation of the inverter - sometimes an error code can simply communicate that there is no DC power being received from the solar array…usually the cause of this is because it’s night time!
I have a table of error codes for my inverter and what each means in plain language (a web page, I don’t have a table in OH3). I am able to access these codes in OH3, I currently have them published to my Sitemap in raw form i.e. as they are read from the channel of my Symo Inverter Thing, which is a number.
I would like to create an Item to hold the interpreted String State of the inverter error code, as updated from the appropriate channel of the Symo Inverter Thing.
Is there a way to create a lookup table in OH3 so that in a rule, I would be able to read the error code as it is updated from the appopriate channel of the Symo Inverter Thing and update an Item with the equivalent plain language state (in a string)?
I could then use the string item in my sitemap.
