BlueTemp: BLE Thermometer

Read your Bluetooth thermometers and hygrometers on one screen. BlueTemp is a temperature and humidity monitor for BLE sensor tags: it picks up the temperature, humidity and battery they broadcast, with no hub and no vendor cloud. Name each sensor by room, watch the readings live and get an alert when a sensor goes quiet. YOUR SENSORS ON ONE SCREEN • BlueTemp opens on your sensor cards: temperature, humidity and battery for each one, updating live while it listens • Tap "Add sensor" to see the thermometers and humidity tags broadcasting nearby, and tap one to add it • Give each sensor its own name, colour and note: nursery, greenhouse, fridge, garage • See which sensors are in range and how long the others have been quiet SENSORS IT READS • Xiaomi thermometers flashed with ATC1441 or pvvx custom firmware • Xiaomi and Qingping sensors that broadcast unencrypted readings • Govee thermometers and hygrometers that broadcast their readings • Ruuvi tags (data formats 3 and 5) • BTHome v2 sensors, such as Shelly BLU, that broadcast unencrypted readings Sensors that encrypt their broadcasts (for example a Xiaomi LYWSD03MMC on stock firmware) show up, but their readings cannot be read without the sensor's key. ALERTS • Get an alert when a sensor comes into range or goes quiet • On Android you can keep watching with the screen off (a persistent notification shows while it runs, and it uses some battery) GOOD TO KNOW • Readings are live: BlueTemp shows what each sensor is broadcasting now, while the app is listening • Each card shows the lowest and highest temperature since you opened the app; it does not keep a longer history or draw charts, and it does not alert on temperature or humidity thresholds • Sensors must be within Bluetooth range of the phone (usually a few metres to a few tens of metres) • BlueTemp is not affiliated with Xiaomi, Qingping, Govee, Ruuvi or Shelly WHY IT ASKS FOR LOCATION Android treats some Bluetooth broadcasts as a location signal, so BlueTemp asks for the location permission to see every nearby device. It never reads your position or collects any location. Free sign-in keeps your purchases and settings on every device. ADVERTS BlueTemp is free with ads. PRIVACY • Nothing BlueTemp hears is uploaded, and nothing about the devices around you leaves the phone • Nothing you scan is synced • What you save stays on the device until you share it yourself • Counting which features you use is off by default, and the counts stay on the device Install BlueTemp and see every room's temperature and humidity at a glance.
