Got the same issue since updating to 06.2025.

Same here

Jun 13 '25 04:06 MikeBP13

I'm having the same problem. My automations have gone crazy.

Jun 13 '25 06:06 ihsancelebi

Last evening it was happening every other minute. This night it was actually occurring almost every other second.

I also have a Switchbot Lock Ultra and this behavior isn't happening there.

@zerzhang For sure. It happens a few times during this capture

home-assistant_switchbot_2025-06-13T11-28-42.137Z.log

Something i noticed that its only happening when the lock is physically unlocked. When its physically locked the state is stable

@remcom Thanks

Jun 13 '25 13:06 zerzhang

@zerzhang Maybe its related to the fix Fix encryption disconnect race by @bdraco in https://github.com/sblibs/pySwitchbot/pull/355 that is in version 0.66.0 while 2025.6 is still using 0.64.1 (https://github.com/home-assistant/core/blob/2025.6.0/requirements_all.txt)

Same issue here. Slow and toggling.

Jun 15 '25 05:06 daicol

I have 2 SwitchBot Lock Pro devices, same HW, same FW, but only one lock exhibits this behavior - the one configured with night latch. When the lock is unlocked, I get multiple sets of (is unlocking, was unlocked) events.

Jun 15 '25 15:06 MikeBP13

Yeah, joining the bandwagon here. When I unlock my SB Pro, it does unlock physically, but it doesn’t send any signal back to Home Assistant. So last night, for example, the door stayed unlocked the whole night, but HASS still showed it as locked—as if everything was fine.

Not trying to make a big deal out of it, but it's definitely uncomfortable being unknowingly unlocked, especially in a place where "random" people like to check if someone’s home or away during summer.

I'm manually locking it for now, but wondering if there’s something on the horizon or maybe a temporary workaround—like rolling back HASS to before 2025.06?

Thanks a lot for all the hard work ❤️

Jun 15 '25 16:06 mariosemes

Update: the lock which I thought it worked, doesn't. When unlocked, it is shown in HA as locked at one point (random, minutes later). So, bottom line, none of the locks have the correct status in HA. There's something wrong with the latest update.

I managed to get the SB Pro working perfect again. I set the Bluetooth to passive scanning and that came good. SB Ultra is still unusable though. Will try moving closer to the RPi to see if that helps as a test

Having a similar problem here with the lock Pro connected to home Assistant via Bluetooth proxy. Specifically the lock state is toggling locked and unlocked when I open and close the door. I do not have an issue with the lock state otherwise.

Same problem... :(

Update: Tested it next to the Pi and it worked fine. My issue is signal related.

Additional information on an environment exhibiting the issue:

Was working fine in 2025.5.x Home Assistant Yellow running RPi 4 ESP32-based Atom S3 Lite Bluetooth proxies running the example build in active mode

Lock is the only device currently attached to its proxy:

Thank you in advance for your time working on this issue.

I saw a v3.0 firmware that at least fixed the behavior using the App and the button in it, but HASS still has issues.

Jun 19 '25 12:06 mariosemes

@mariosemes Where did you see that 3.0 firmware? The latest for me is 2.9

@mariosemes Where did you see that 3.0 firmware? The latest for me is 2.9

I was spamming SwitchBot support in the chat on their website. They just told me that they pushed a 3.0 firmware, I should open up the the official app and it should popup. Well, it happened, opened up the app, selected Lock Pro and I got the UPGRADE AVAILABLE.

It did fixed the lock, I'm able to use it outside Home Assistant, but HASS is still struggling to get info from it.

I upgraded my Bluetooth to usb 5.3 adaptor, passive scanning. Has been working great so far (1 day) on my RPi 4B.

Jun 19 '25 21:06 daicol

Any progress on the fix?

Jun 20 '25 06:06 MikeBP13

Same here, not 100% sure, but looks like that it moves to state "locked" when the door (not the lock) is shut, then after X seconds it moves back to "unlocked"

Jun 20 '25 12:06 dbuchet

I see no FW updates for the Pro lock in the official app. The behavior of the locks in HA is still erratic and my automations are useless at this point.

To top it up, at random times, the locks get disconnected, even though there are BLE proxies in vicinity and the locks connect to those. With the previous version, the setup was rock solid for 6+ months.

Randomly, one of the locks is reported as unlocking and remains in this state. The other is reported as locked, even though it is unlocked.

The status in the official app is always correct.

I'm using the Bluetooth integration approach if it helps.

Jun 21 '25 08:06 MikeBP13

We have submitted a PR https://github.com/sblibs/pySwitchbot/pull/360 fix this problem, please wait Or try setting Bluetooth to passive mode, which should solve some problems
