Hi all
I have had my inverter, battery, and data logger firmware all updated to the latest firmware but I still don’t see the 5 sec refresh.
Sometimes when I open the app I do see a circle that counts down from 5s to 0, it cycles through this about a couple of times but then disappears.
Any suggestions.
Inverter H1-5.0-E-G2 , master 1.59, slave 1.04, manager 1.79
Battery ECS2900
Datalogger W4 v4.14
Some have had success with either physically removing it, and inserting it again.
Rebooting your inverter & battery.
Re-pairing up the wifi network to the datalogger.
I have also included a wifi signal graph (App ->Device -> Data Logger -> Network Type) so you can check signal strength.

That's interesting, my 5 second update is a bit flaky some days, but I didn't know I could check signal strength seen by the datalogger.
Sadly I just see 'No data' on that page. Maybe down to different datalogger type? Mine is WW.

Hi. Thanks for the reply.
I don’t see a signal at all on that page. Maybe that’s the issue then. I have rebooted my inverter twice now and still no change

It has been sometimes flaky with mine also, I just wait a bit and check later.
I also didn't know you could see that graph until today, there was a billy basic 4 bar strength indicator beforehand for me.
I have data for today, mine is W6.
Not sure why there is a difference, but I guess there are variants for reason know to Fox.
You could also reboot the home router, that is another choice that I forgot to mention before. It can also be an idea to stand by your inverter with phone/tablet and measure signal on another device in that location?
Yeh tried rebooting the router too. My data logger is the W4. I might need to try putting an access point near the inverter but then I think that if the signal was an issue then surely I wouldn’t get the delayed values either?
The 5s refresh data is only sent to local interfaces (App or the cloud v2 website)
The main data is every 5 minutes, stored and pushed to Fox servers, used for long term stats. IIRC this can be saved and batch uploaded, when signals are bad?

This has so far been a very flaky day for 5 second updates. Not working at all.
The datalogger is showing the usual green and red lights.
Be interesting to hear if anyone else is having 5 second update issues today.
(I ask because in the past I'd always assumed that occasional absence of 5 second updates was because of throttling by FoxESS servers, but MB's post above seems to imply that their servers aren't involved and all communication is local if I'm reading correctly?)
And now they're back!
