Hi @PPG, please tell us your AC180P’s SN number, and then we will help you downgrade the firmware.
Hi @PPG, Thank you for getting back to us so quickly.
The entire SN number is AC180P2438000641876.
Now I have applied to downgrade the firmware for you.
Our IT department will push the corresponding firmware to your unit in 24 hours. Please upgrade it tomorrow.
Please do not load any device when upgrading it.
Please let us know if it works.
Hi @PPG, Our IT department informed us that you have not upgraded yet, and therefore, downgrading is not possible.
Additionally, the Bluetooth password is hardware-related and cannot be disabled through a firmware downgrade.
The only solution is do not setting a password, which should not affect the use of your HA system.
Hello @BLUETTI_CARE - I too am having problems integrating my AC180 into Home Assistant due to the encryption on the Bluetooth connection. I have seen this post and went looking for the option to disable the Bluetooth Password, but the only option I see is to set a new password. Leaving the password field blank does not pass validation, which requires at least 6 characters for the password. Is there a different way to disable the BT encryption?
Thanks!
Hi @jdwannam, For this issue, please log into the Bluetti app, go to settings, and then to the Bluetooth connection password page.
Select “No Password” so that you don’t need a password for verification.
I hope it does help.
Hi, I am facing the same issue with a new AC180 and i just wondered if you were able to find a resolution. From my research the HA Bluetooth integration and the MQTT Add On will fail to work due to the new BT encryption. Maybe someone will find a workaround or Bluetti may come to their senses and find a way for 3rd party access…
Thanks for any info you can provide.
Unfortunately no, I tried setting and then deleting the password in the app, I’ve also tried just unbinding the unit from my app but it still does not show any data within home assistant.
Thanks for your reply… hopefully there may be an update one day that will help HA users.
