Fronius Solar Web - data logging issues

Recommended Posts

I had a system installed this week with a Fronius Primo 8.2  & smart meter and am having trouble with the data logging.   

Day 1.   system online ~midday.    Installer hadn't set up my viewing permission so I didn't check data at all.

Day 2.    Logs fine from  start of Day 1 to ~7am day 2 but then stopped logging until ~4pm.     At 4pm both the website and app accurately updated the missing 7am to 4pm data and continued to log fine to end of day.  

Day 3.   Logged fine from midnight to  ~7am then stopped  logging,  until ~1:30pm,  at which time the website updated but data was not accurate  (shows constant 3.91kW for the 6.5hrs duration but  when actual was  ~3 to 8kW).    It  just logged that one data point at 1:30pm then nothing since.          The solar web iphone app  history page is  still showing yesterdays history so is even worse than the website.

I've contact my installer and he's not sure what the problem is.

I'm suspecting my wifi as the inverter is on the edge of coverage,   but the fact the live data always seems fine makes me think not.   


any suggestions??   

anyone had similar issues in the past or lately?

@manchu I'd suspect WiFi connection reliability. I never count on wifi, and always run a cable if possible. My Fronius is hard wired, and I never have issues (unless I'm fiddling, which I'm prone to).


Another thing to make sure of is that Night Mode is set to 'ON' in your inverter. If you have a Fronius Smart Meter, you MUST have night mode enabled so your logging works correctly.


I've made a little video for you here on how to do it.

I think you're right.    A home network upgrade is on the cards so I'll  run a cable.

Thanks for the tip and vid.   I checked and it was already ON.  

The logging does seems better now than the first few days.   I haven't noticed any big delays (several hours) in history updating recently,  but that might be because I'm not looking at as often now the novelty has worn off a little.
