Switchbot Meter not detected

dreifritz commented 1 week ago

The problem

Switchbot Meter works with Switchbot App (local BLE connection). Six Govee Bluetooth Thermometers, Shelly Bluetooth dongle, works flawlessly. Tried to add Switchbot Bluetooth integration, terminates immediately with "No unconfigured devices found" message. Active scanning enabled. Shelly dongle log and bluetooth.remote_scanners both show entries with correct device address: "E8:89:3E:EC:8F:82", see log file entries attached

You either have active scans disabled or the SwitchBot device is too far away from the Bluetooth scanner and it can't hear it. SwitchBot requires active scans for discovery.

Hey there @danielhiversen, @renierm26, @murtas, @eloston, @dsypniewski, mind taking a look at this issue as it has been labeled with an integration (switchbot) you are listed as a code owner for? Thanks!

As I wrote above, I do have active scans enabled, the Switchbot device is 2 meters away from the dongle, and it is detected by the Shelly dongle and listed in the HA scanner report. What else do you need to prove that the Switchbot device is present and visible?

    "data": "shelly_notification:208 Event from script:1: {\"component\":\"script:1\",\"id\":1,\"event\":\"ble.scan_result\",\"data\":[2,[[\"e8:89:3e:ec:8f:82\",-70,\"AgEGDv9pCeiJPuyPgtgDApFC\",\"\"]]],\"ts\":1730909572.42}",

Active scans aren't happening or the device isn't sending a scan response. The second value is empty

https://github.com/home-assistant-libs/aioshelly/blob/78fd1ed4b1ece333301f26ae42bc8d5f3529fab2/aioshelly/ble/parser.py#L40

"AgEGDv9pCeiJPuyPgtgDApFC", "" <--- there should be a scan response here

Its likely one of the following problems:

Active scans aren't enabled in the shelly integration
It is a bug in the shelly firmware or integration and its not actually enabling scans
The switchbot isn't responding to the scan request or its bug in the switchbot firmware

Great. As a user I am totally lost. How can I find out if it's a Shelly integration bug or a Shelly firmware bug or a Switchbot firmware bug? Or something else? Strangely enough there are reports of other users that their Switchbot Meters do work. I am wondering why the Switchbot integration terminates immediately within a fraction of a second. I would have expected that it at least tries to find a device for some time.
