Bluetti EB3A has been behaving erratically

Hello,
Until now, i was satisfied with the EB3A. I use it in case of power supply outage for a respiratory machine.
Since this morning, my Bluetti EB3A has been behaving erratically.
The bluetti activates itself and the light switch turns on and off by itself, activating and deactivating the light without any intervention.
I upgraded it via the smartphone, without solving the problem
Could you help me, please ?

Device name: EB3A2226002773927
Serial number: 90388QE22380543

Hi @DenisTH, I am sorry for the inconvenience. It seems that a return for repair may be necessary.

Please contact us via private message and provide your order number and email address. We will arrange after-sales service for you.

Thank you for the answer. Not under guarantee any more
It comes back to normal as it appeared ??? Maybe the high level of humidity (94% these days) in Thailand

Hi @DenisTH, Thank you for letting us know.
I agree with you, maybe it is affected by the environment.
