Current app version 2.3.5
IOT 9041.06

Hey @neosss
welcome to the bluetti community forum!
There are multiple things that can trigger wrong or missing data.
1.) There might be a discrepancy due to data transmission issue between the device and the App. @BLUETTI_CARE Can check it with the SN
2.) State of Charge (SOC) inaccuracy: Another possibility is that the SoC readings might not be accurate, leading to inconsistencies between reported solar prodiction and actual SoC levels.
greetings

Thank you for @Selfmadestrom’s answer. Currently, there have been a few similar cases reported. Our R&D department has resolved this problem with the new IoT firmware.
Hi @neosss, Could you please tell us your AC500’s SN number? Then we will push the new firmware to your machine.

Hi @neosss, Thank you for getting back to us so quickly.
But the IOT version you provided is not correct. I have attached a screenshot for reference.
Can you check it again? Then we will apply to push the new firmware soon.
Hi @neosss, Now I have applied to upgrade your system to our IT department. They will push the IOT v9041.09 to your machine in 12 hours.
Please upgrade it tomorrow. Please do not load any device when upgrading it.
I’m Find solution!
Strange things, but only in 2.4GHz WiFi in mode wpa2-personal and lower it works
In mode wpa2/wpa3 personal not works, but before upgrade all was good.
Now this versions is installed
Please, give me previous version of firmware)) it works fine with my WiFi router
Hi @neosss, Our devices indeed only support 2.4G WiFi. We’re not sure why the upgrade affected your WiFi signal, but we’ve already submitted a request to revert to the original IOT version v9041.06, as per your request. This process will be completed within 12 hours.
Please proceed with the downgrade tomorrow, ensuring that no loads are connected during the process.
Thanks for fast response
Now, today I received new firmware IOT for rollbak.
Problem with connect in wpa2/wpa3 mode fixed. All works with wifi.
But after installing upgrade, message with upgrade button still standing.
How to fix it?
Upgrade installed, issue fixed, only message leaves
Hi @neosss, I am glad to hear that the problem is resolved.
I have informed our engineer to delete the upgrade message. It should be fulfilled in 12 hours.
It will not disturb you again.
Meanwhile, please remember to @BLUETTI_CARE when you need take my attention. WIthout it, I can’t find your update information in time.
