Bluetooth thermometer & hygrometer app: temperature and humidity in every room
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.
