[Hub Mini] WoIOSensor Outdoor Meter readings not bridged via OpenAPI v1.1 (hubDeviceId: "000000000000", temperature/humidity = 0)

[idrnet]

Summary

The Hub Mini (WoLinkMini) appears unable to bridge Outdoor Meter IP65 (WoIOSensor) readings to the SwitchBot cloud. All OpenAPI v1.1 device-status calls return zero values and a null hub binding, despite the devices working correctly inside the SwitchBot mobile app.

Filed at the explicit redirect from SwitchBot Support (ticket #1250865, Gigi, 2026-05-20).

Setup

• 1× Hub Mini CB — MAC CF:2C:08:03:C1:CB (Matter version, firmware up to date 2026-05-18, LED solid white = normal)
• 2× Outdoor Meter IP65 (WoIOSensor) — device IDs CA5F45463F27 and CA5F4646671E, firmware up to date, fresh AAA batteries
• All on the same SwitchBot account
• All devices visible and operating in the SwitchBot app

Observed via OpenAPI v1.1

• GET /v1.1/devices → all three devices listed, but every entry has "hubDeviceId": "000000000000"
• GET /v1.1/devices/{sensorId}/status → returns

  { "temperature": 0, "humidity": 0, "battery": 0, "hubDeviceId": "000000000000" }

  for both sensors
• GET /v1.1/devices/{hubId}/status → returns { "body": {} }
• Auth + signing work (HMAC-SHA256), API responds HTTP 200 / statusCode: 100

Steps attempted

1. Firmware updated on Hub Mini and both sensors
2. Hub Mini power-cycled multiple times
3. Sensor deleted from account and re-paired (~10 cm from Hub Mini)
4. App v9.26 — no "Store Data to Cloud" toggle visible in sensor settings (gear icon shows: alert conditions, calibration, comfort level, third-party services, NFC, help & feedback, firmware & battery, device info — that's all)
5. "Export Data" at bottom of graph view does not work

Question

Is the Hub Mini (WoLinkMini) actually able to bridge Outdoor Meter IP65 (WoIOSensor) readings to the SwitchBot cloud — populate hubDeviceId and stream temperature/humidity via OpenAPI v1.1 — or is this only supported by Hub 2 or later?

A clear yes/no in the docs (ideally a compatibility matrix of hub_model × sensor_model → OpenAPI bridging supported?) would prevent other users from hitting the same wall.

Hub 2 already ordered as a workaround. Answer needed to confirm whether this is a Hub Mini limitation by design or a firmware/account issue.

Thanks!
