Add support for switchbot presence sensor

[lukasmalkmus]

👋 First-time contributor

First contribution to Home Assistant. Created with AI assistance, thoroughly reviewed and tested with actual hardware on HA 2025.11.1. All entities working correctly.

Compact implementation (~93 lines, mostly tests) following recent merged PRs (#155124, #155309). Happy to receive feedback and make adjustments!

Proposed change

Add SwitchBot Presence Sensor support to the switchbot Bluetooth integration.

The device combines mmWave radar, PIR sensor, and light detection. Already supported by PySwitchbot 0.73.0 (PR #410) and the switchbot_cloud integration (#155309), but missing from the Bluetooth integration.

Changes: Add device type to supported models list and configure platforms (binary_sensor + sensor). Pattern matches Motion Sensor.

Entities: Motion + Light (binary_sensor), Battery + Light level + Signal strength (sensor)

Screenshots

Type of change

• New feature (adds functionality to existing integration)

Additional information

• This PR fixes or closes issue: fixes switchbot bluetooth reports "no devices found" for switchbot presence sensor #155862

Checklist

• The code change is tested and works locally.
• Local tests pass (will pass in GitHub CI - macOS has Bluetooth dependency issues)
• There is no commented out code in this PR.
• I have followed the development checklist
• The code has been formatted using Ruff
• Tests have been added to verify that the new code works.

If the code communicates with devices, web services, or third-party tools:

• The manifest file has all fields filled out correctly.
• Updated derived files by running python3 -m script.hassfest (will run if requested)
• No new dependencies added (uses existing PySwitchbot 0.73.0)

Testing

Tested on HA 2025.11.1 with real hardware. Device discovered automatically via Bluetooth, all 5 entities created and reporting correctly.

Test added following climate panel pattern (#155124), verifying entity counts and attributes.

Hi @lukasmalkmus, thanks for this PR!

JFYI, the Switchbot Smart Radiator Thermostat support by @zerzhang has just been merged: #155123
It changes the same files as yours, so you may need to rebase, and it can also be useful to validate your code.

Thanks again

There's a merge conflict

This shows "motion" in your screenshot. As its a presence sensor, it would likely be better to show "occupancy" instead, with also the house icon instead of motion icon.

[lukasmalkmus]

[lukasmalkmus]

Not sure about this bit but I didn't want to interfere with existing sensors by changing this, globally.

[borgqueenx]

I would say the light sensor can be called that as well. Unfortunately no lux values so not a lux sensor, but still a light level sensor. Just trying to help out with correct labeling, hope it can be merged soon, bought 7 of these in the hope they were supported, but they were not (yet). Haha.

[lukasmalkmus]

From what I understand, this might not just be the labeling, which is why I was careful.

And yes, same mistake. Bought a bunch just to find out they are not (yet) compatible, lol 🤦

Oh hi there @lukasmalkmus 👋

Thanks for the pull request. However, the tests seems to be failing right now. Can you take a look and make sure they pass?

Thanks already! 🙏

Hi,

I rebased on latest main, every check seems to pass, now (apart from the ones I can't trigger as I miss workflow approval).

EDIT:

I think most of the comments here are a result of frustration about the poor marketing from SwitchBot. I bought the sensor because the product page explicitly stated that it supports Home Assistant without a Hub.

SwitchBot Bluetooth being a gold rated HA integration, I thought I'm just doing something wrong and reached out to SwitchBot support. After going through the usual first-level support shenanigans of providing screenshots, diagnostics, etc. it turns out the support is just not there and scheduled to be available Nov. 31st. A little more detail in the marketing material would have helped many of us :)

So we now we have this PR and this other one for the same goal and both not yet merged.
Hope in a conclusion of this story, my SwitchBot Presence Sensor is waiting for a "real life" with HA :-)

[joostlek]

Can you please stop force pushing? I pushed changed to get it mergable and now it's overwritten again...

I'm not emotionally attached to this piece of code so I happily accept the other PR being merged (not that I have any authority over that 😄) since the author seems to be affiliated with SwitchBot.

(I still incorporated the missing battery_range sensor from #157148 for completeness).

And finally the tests pass, forgot to update them.

[joostlek]

I am going to check with Switchbot on the battery range, as I think it's weird to both have battery state and battery range. It doesn't add much IMO (why add a vague option when you have a precise one available)

tests fixed

Thanks @lukasmalkmus @joostlek

Ah, my bad! I Didn't see that. I recently adopted Jujutsu and now I developed a habit of force pushing. Forgot for a second I'm not alone on this branch.

Thank you all for the help getting this merged!
