Hi @ftrueck
Thanks for your work on github btw.
Bluetti will publish a official Homeassistant integration on newer products (hope on older units too)
Dont have any details like how much information we can get out of the official plugin, but its a good begining.

Hi @ftrueck, Regarding this question, please note that the AC200L records apparent power, which includes active power and reactive power. Therefore, the value displayed will be higher than that recorded by your electricity meter. This is normal.
Thank you to @ecat and @Selfmadestrom for their explanations and analyses—they are very valuable!
Official HA integration would be fantastic, assuming high reliability, WiFi (better yet, wired. I can dream ;) ), local connection.
On Bluetooth, my first reaction is always, short range, unreliable, requires some app and a smartphone. Apps go out of date and I hate smartphones!
And @BLUETTI_CARE thank you for your feedback too.

I see.
Though the info is not the same.
I guess this is because of the dummy load that the AC200L has to apply to measure the grid.
Hi @ecat, Thank you for sharing your valuable opinions.
We have indeed received a lot of feedback from users mentioning that Bluetooth connection is inconvenient.
Therefore, we have incorporated more built-in WiFi connection functions in our new models, which are more user-friendly.

Hi @ftrueck, I appreciate your interest in BLUETTI.
This is the operating logic we set from the initial design stage, and it is also reflected in most models of our power stations.
@BLUETTI_CARE Hello! So, to sum it up:
- We do have parasitic drain from AC when we should not (because we specifically use UPS Timed mode to not drain AC power at hours when it costs more). The amount is different for different battery drain consumers, but it is always > 0.
- Can this be fixed/prevented/changed in any way by firmware update, or is it 100% hardware design?
- If not possible, I add my voice to requests to add WiFi API control possibility, to turn off smart power plug for AC input from Home Assistance by time of the day.
For me, only WiFi will work, because I don’t have separate server, like most of the people, but everyone has phone and router, both are running 24/7, both can use WiFi connection and scripts/apps for automation.
P.S. I have a 200PL, not an 200L, but I suppose it’s the same in that regard.
Thank you.
Hi @snmya, Thank you very much for your valuable feedback. At the moment, we don’t have new firmware available to reduce power consumption, we’ve already passed this suggestion on to the app team for further discussion. However, we believe this is an unavoidable objective behavior and not a hardware issue.
If you’d like to request API control access, please message us directly and provide your email address, as we’ll need to send the documentation via email after granting access.
I could narrow down the bluetooth problem.
It seems to be related to PV input and reconnection of bluetooth multiple times in a short amount of time.
The unit gets stuck in the following way:
- Bluetooth connection does not work anymore
- Bluetooth icon is not showing in display
- Bluetooth icon is on in settings screen
- Power button does not react
- AC, USB and DC button still work
Now the interesting part:
- If I only disconnect PV input the unit becomes sort of responsive again.
- Bluetooth connection does still not work.
- Power button works now
So I can power down the unit then and start it again, then it works normally again.
Hi @ftrueck, Thank you for your observation and analysis. However, after our discussion, we believe this should just be a coincidence. Since the Bluetooth module and the PV module are separate, they shouldn’t be related. Could you please take a video, upload it to a cloud drive, and share the link with us to have a look?
Please note that if you turn off the Bluetooth module, Bluetooth will be disabled, and it must be turned on to use it. As for the issue of being unable to power off, it is caused by the automatic activation due to energy input.
I think it was not clear enough what I told:
- The POWER button of the AC200L does not react to pressing
- Bluetooth is activated in settings page of the AC200L unit
- Bluetooth connection does NOT REACT in this special condition
- AFTER disconnect of PV cable the POWER BUTTON immediately reacts and turns off the AC200L unit
I know that these are separate modules. BUT the mainboard does not turn off the unit while the PV cable is connected and Bluetooth does not work when the crash situation happened. As these crashes are random, it is very hard to do a video. Next time it happens I will try to make a video demonstrating the whole situation.
Just FYI, if there is any charge source connected (either PV, DC, or AC mains) then the power button will not turn off the power station – this is the case for all Bluettis.

Ah, now I understood. OK, that eliminates that connection. The bluetooth problem remains anyways.

What i forgot to mention:
- Bluetooth was turned on in settings, but connection to AC200L was not possible
- Turning off bluetooth and turning it on again did not change the situation
- Only after restarting the unit bluetooth worked again
Hi @ftrueck, Thank you for providing the specific information.
Could you try replacing it with another mobile device and testing? If you can provide a video, it will indeed help with the analysis.
Thank you, @hnymann, for your reminder and explanation. It is very helpful.

Hi Bluetti,
i too have the same strange grid draw during peak time in TOU, perfectly described by ftrueck, with only capacity loads (router/PC etc).
Would be awesome a firmware upgrade with a new custom UPS mode option to disengage GRID completely (like we do with a smart plug, but without that), keeping SOC LOW as threshold to re-engage GRID eventually. Think this like the option “charge from grid” but this time the focus is to block GRID completely until you reach SOC LOW.
I think many of us use TOU to bypass grid during the night and with only capacity load connected (eg: computer / router and so on), it’s clear to me that you can’t redesign existent hardware to better support this kind of loads, but i think you can introduce this new option for advanced users like us, what do you think?
Regards,
Luigi
Hi @luigi_tomaselli, We would like to confirm if your power station is the AC200L as well.
Your user experience matters a great deal to us, and your feedback is highly valuable.
Rest assured, we have formally passed your opinions to the R&D team, who will review them when optimizing product performance.
Yes, AC200L.
Regards,
Luigi

@BLUETTI_CARE it really would be great benefit to be able to control the grid-ac relay via app/bluetooth. If your hardware designers were smart they made it controllable via firmware. Then this would be a no-brainer.

Hi @ftrueck, Thank you for sharing your feedback. We have submitted the relevant information to our R&D department for their review and consideration.
We agree that your suggestion would bring great convenience to users; however, the R&D process may involve various challenges that need to be addressed step by step.
Once again, thank you for your valuable input—it plays an important role in helping us optimize our products and services.
