• Set-up in seconds via Ubibot App or PC tools. Connect using 2.4 GHz WiFi, no hub required (5 GHz WiFi not supported). Easy data access anywhere via the app or web console. Works with IFTTT, allowing you to build automated links with other smart devices
• Swiss-made sensor chips, accuracy ensured. Works in environments - 20ºC to +60ºC (-4 ºF to 140 ºF), 10% to 90% RH. External probes (B07FKCWPLY) can be connected in extreme conditions (-55ºC to 125ºC). Suitable for a greenhouse, cold room, laboratories, cigar cabinet, instruments storage, and more
• Free history tracking. Free 200 MB cloud storage is enough to store data for up to 2 years on default settings. Online data can be exported to the computer in PDF or CSV files. The device also has large internal memory that can store up to 300,000 pieces of data, ensuring no history gap when the network is down
• User-oriented design

Custom settings are available with many features:

• Measuring rate and sync rate: Minimum 1-minute
• Temperature unit: Celsius and Fahrenheit
• Calibrate the readings on the platform end
• Individual device name settings, recognize the device among the list by a glance
• Power supply: 4 x AA batteries or Micro USB cable power
• Customized alerts can be sent to multiple users. You can be notified when the device goes offline, sensor readings are out of the preset range, low battery, etc. Available alert modes include Email, app notification, HTTP API, IFTTT, SMS, phone call
• Advanced solution for temperature and humidity monitor
• Our cloud-based IoT platform offers advanced data analysis and management. With the app, you can manage all of your devices in one Ubibot account. Set alerts for sensor readings and offline status, the device will notify you by in-app notifications, email, IFTTT notifications, SMS text, and also voice calls, allowing you to respond promptly before costly damage happens. Please note, that charges of credits in your account may apply when you choose SMS text and voice call alert modes
• There is no subscription fee. All devices come with a free plan that contains 200 MB of online storage and 1 GB of outbound traffic. The free storage is enough for up to 2 years of usage. The platform supports free data export and PDF reports. Once the storage is used up, you can delete the data and reuse
• The device also has large internal memory that can store 300,000 records, which means once the network is disconnected, your data won't get lost
• The data sync interval can be set by you. This allows you to balance battery life against the frequency of data capture. With a data sync interval of 15 minutes, the device has a battery life of up to 8 - 12 months using 4 AA alkaline batteries
• We also open up our RESTful API, offering professional users the chance to develop their monitoring solutions. If you need to deploy local API with our devices, we can also assist both in hardware and software
• The sensor precision can be affected by extreme environmental conditions. We recommend you avoid using it outside the optimal operational conditions listed above. For usage in extreme conditions, you can conduct an external temperature probe to help with monitoring. The probe is also available in our store
