UbiBot WS1 is not waterproof. The optimal operational environment is 10% to 90% RH. Long term of exposing to high humid environment over 90% may cause damage to the device.

If used for a freezer/fridge, it’s best to connect a DS18B20 external temperature probe, and put WS1 outside of the freezer/fridge.

WS1 can only work with 2.4GHz WiFi network. 5GHz WiFi is not supported.

Real-time and history data

The UbiBot Platform is a cloud-based IoT platform where all measured data are uploaded and stored. Via Ubibot App and Web console, you can view the current data as well as historical data in graphs. Adjustable Y-axis scale allows you to view any tiny fluctuations in the curve.

Customizable alerts and bulk operation

Setting and receiving alerts of your devices help you get notified of the conditions in time. When you have many devices to manage, it’s time-consuming to set each alert rule one by one. So we developed bulk operation module with which you can set the same rule for many devices at a time.

Free data export

On UbiBot Platform, you can download the history data in CSV or PDF format. The CSV file only contains raw data, while the PDF file is a summarized report with average, maximum and minimum value within the chosen period. It’s much easier to read and archive.

Device sharing and bulk operation

Central control is available for business users because of no limit to device quantity in one account. And bulk operation applies to sensor settings, alert, and remote control routines. In the meanwhile, devices are allowed to share with others, which means distributed management by different colleagues.

Intelligent automation in UbiBot platform

UbiBot is committed to building intelligent industrial and home ecosystems. By integrating temperature and humidity sensor and smart plug SP1 in one system, automated operation is achieved through data linkage. For example, switch on the fans when temperature rises to 30 C.

Data forwarding

UbiBot is an open platform that provides cloud-based services while supporting customers to use their own storage servers. With the data forwarding service, you can forward the data collected by your device to your own private URL to protect privacy.

Location tracking and logging

UbiBot GS1-PL4G1RS is embedded with GNSS (Global navigation satellite system) for positioning. Through mobile data communication, real-time location information is transmitted to the platform and recorded. The UbiBot platform integrates this data and plots it into a trajectory map and presents it.

Platform-based calibration

UbiBot platform supports data calibration both on the platform level as well as the device level. One-step calibration, instant display, no impact on historical data.

SIM card management

When using UbiBot Global SIM to transfer data, you can manage it by yourself. Unlike other SIM card with standard monthly fee and traffic amount, our SIM supports many types of plans. Choose the one that suits you now, and change to another next time. No extra charge after a few months of arrearage.

1*DS18B20 temperature probe

- UbiBot WS1 supports 1 x DS18B20 external temperature probe. Temperature range and option can be found here.

- With a Micro-USB Cable Splitter, WS1 can connect 1 x DS18B20 and external power-supply at the same time.

If used in continuously high humidity over 90%, we suggest to using UbiBot water-resistant case and connect DS18B20 external probes.

1. Does the device collect data when the network is unavailable?

Yes. The device continues to monitor the environment even when no network is available. It stores the data in its on-device memory and will sync it when you move it to WiFi environment. Alternatively, you can manually export the data via our PC Offline Tool or WiFi AP.

2. How to reset the device when my WiFi router password is changed?

Repeat the device setup steps and follow the on-screen instructions. Note: you need to type in the new WiFi password. All your data are kept unchanged when you changed the WiFi password or even you move the device to a new location.

3. What kind of probe can be connected with the device?

The WS1 device supports 1 DS18B20 temperature probe. When you need both USB power supply and external probe connection at the same time, you can use the Micro USB Splitter Cable Adapter (One Male to Two Female).

4. Is there any subscription fee for using the platform?

There is no need of subscription to use the UbiBot Platform.

Each device comes with the free plan on UbiBot platform that offers 200 MB storage and 1 GB outbound traffic. The 200 MB storage is for lifetime and 1 GB of outbound traffic is rotated monthly for each device. But any balance of the outbound traffic will not roll over to the next month. For example, if you have 500 MB outbound traffic unused this month, you still have 1 GB next month. The free 200MB storage is enough to store over 2 years amount of data in case of your device takes temperature, humidity and light sensor readings every 10 minutes.

You can also pay for larger amount of storage and outbound traffic. Please go to the “Pricing” page to see details.

5. Can the device powered by USB power supply?

Yes. The device supports both AA batteries and Micro USB power(5V2A). The device can preferentially use USB power if both USB and batteries are available. In this case, you can insert 4 AA batteries as a backup for the power supply in case of socket power goes off.
Rechargeable batteries are also supported, but please note the device won’t charge them when USB supply is plugged in.
