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]

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 🤦

[borgqueenx]

@joostlek i see you requested changes but it seems complete now? Is this ready now to review/merge? Or something remaining?

Hello and thanks for this, I purchased mmWave Switchbot Presense Sensor and I would like to see it in Home Assistant (via Bluetooth) like I already do with my others 20+ Switchbot devices.
So, when this PR will merged?
Many Thanks!

We are dependant on the core developers who have write access.
Maybe @zerzhang can help as he made the pyswitchbot update?
Hope it can be merged soon so that we can have the sensor working in next HA-core release.

Hello @zerzhang can you review and approve this PR?
Thanks.

For all, I have had a Chat with the SwitchBot Support and this is what they wrote about adding the mmWave Presence Sensor in the HA integration:

November 30th is the launch date for the Presence Sensor, and December 3rd is the release date for the new version.

I think for the HA version 2025.12.0 it will be included.

If this pr is not merged, that wont happen though. Unless i missed a secondary merge request and this one can be closed?
support probably got that date from their developers so i hope they soon can finish this.

May be someone will approve/merge this or create a new one just before the new version of HA?
I don't know.
What I did for now is also send an Email to the SwitchBot Support asking them when the mmWave Presence sensor will be added in the SwitchBot Bluetooth Integration.

I do not have merge permissions

[zerzhang]

@lukasmalkmus You need to approve the following process and get all the inspection items through.

No, unfortunately I'm not a maintainer and can't merge this PR.

@italo-lombardi changes were made. Unfortunately no response yet from joostlek
Could you or amyone tell how how to proceed if there is anything lacking? It looks good or? A simple change to add device support to the switchbot integration..
