As Bluetti becomes more popular among outdoor enthusiasts I think the app need a passcode to log in a unit. Without this passcode and in a crowded camp ground, people would log in a wrong unit and try to turn on/off. This would be a big headache.
Imagine coming back to camp to find out your unit was turned off by someone and your your ice cream has melted.
I strongly suggest that Bluetti app team would implement this ASAP. Thanks.
This would be bad… but imagine someone doing an malicious firmware update. best cases bricking your device…
worst cases… 
Hi there, any update on this development ?
Hi @LN2023
not hear anything from official side yet.
Maybe @BLUETTI_CARE can give us a update on this topic?
Thanks
Erik
Thanks Selfmadestrom. Hope they include this new feature soon. Many of my camping friends bought other brands last month just because of lack of security in Bluetti apps, even with the price drops.
Any update on this feature ? Thanks.
Hey @LN2023
as far as i know, they implement the feature for some of the powerstation/Home Backup Systems. But cant say for sure which Units.
Greetings

Hi, Is there a way to request this feature for AC180 ? Thanks.
@BLUETTI_CARE Do you know, which models do support this type of pairing and which are in planning?
@BLUETTI_CARE . Hi, let us know that you don’t care anymore about updating your firmware, so I won’t waste my time posting in this forum.
This update is only supported on newer machines.
Hi @LN2023, We apologize for not noticing your message earlier, which caused a delay in our response.
We agree that the Bluetooth encryption feature is very necessary. The new AC50B model has been equipped with hardware encryption chips, supporting this feature. Future models will also include this functionality.
Currently, some batches of the AC70/AC180/AC2A models support this feature. Please provide the serial number from the bottom of your unit so we can confirm.
Thanks to @Selfmadestrom for the help and explanation.
Thank you for your response. The serial number is AC1802316002450078
Hi, can you please tell me if the AC180P supports this feature?
Hi @LN2023, The serial number is different from SN number, it is another barcode pasted on the buttom of the AC180, can you take a photo like this? Then we will check if your AC180 support this function.
Hi @yuriy1975h, can you provide your AC180P’s serial number too? Then we will check it for you.
Hi @LN2023, Thank you for getting back to us so quickly.
I will send it to our factory and let them confirm it, I will contact you when we get an answer.
Hi @LN2023, I am sorry but we found that your machine’s batch does not fall under the Bluetooth encryption feature. As a new feature, we are only trialing it on a small batch of machines. Unfortunately, we couldn’t assist you with this.
Only the newer models starting from AC50B will cover all batches.
Thanks. Can you talk to app people for hardcoding passcode into firmware for each unit. This does not require encryption hardware. Or is there a way to give me the source code and I will figure it out myself. I am fairly good on android app coding. TIA.
