UbiBot WS1 WiFi Environmental Sensor: Temp, Humidity, Light Monitoring | External Probe | Alerts, Schedule Reports & Device Sharing | Local Deployment| IFTTT & Alexa | 2.4GHz WiFi, No Hub Needed

I purchased this to help automate a few smart-home features. The main reason I got this unit was to monitor the temperature and humidity in a room. If the humidity increased behind 50%, it would trigger an event via IFTTT and turn on a room fan via GE-ZWave, wireless smart light switch through a wink hub. Then once the humidity dropped below 50% it would turn off the fan. And as a precaution, I have IFTTT monitor the switched on fan, if it happens to run for more than 60 minutes, it would automatically turn it off. Then, if the humidity is still above 50%, the process will start over again.Also, another use I have for it, is to monitor water temperature in a water tank. I installed a deicer heating element in the tank, and when submerged optional DS18B20 sensor reports to the unit, it uses IFTTT to control a wemo insight switch. When the temperature drops below 30 deg F, it will turn on the wemo insight switch and start the deicer element. When the temperature is above 33 deg F, the insight switch turns off the deicer element. There is a backup protocol I setup with IFTTT just to be sure the deicer does not stay on all the time.PROSNow couple that with all the additional features (Air Temperature, Humidity, Ambient Light Intensity, Vibration Index Sensor, On board memory storage of data, and free 200MB cloud service account to get started, connect to house Wi-Fi, battery or DC powered, add external sensors (two microusb inputs), and connectivity to RS485 devices), I would have to say this is a nice little compact package that could be installed almost anywhere. Granted you will have longer performance if you can power this from an outlet instead of relying on batteries.Very straight forward setup process. With an app that walks you through the setup process.Has an entry level free tier to get you started. If you pay for a subscription and higher tier you can send alerts as SMS and voice call as well as increase the amount of data storage.Able to display history of data in graph view, and select a data-point to view the data (sorta, it is a bit clunky though).Battery or External Power supply.Adjustable data reporting / reading frequency (pre-programmed options 10, 30, 60 minutes. Custom has a minimum 1 minute and higher value in whole number increments).Power saving options.Reports battery voltage and Wi-Fi signal strength.Setup Alerts rules to report as a notification on a mobile device or email (free tier subscription).View data channels on mobile device (personally tested on iPhone X, and other iOS devices) as well as a web interface through their management console portal.Generates API keys automatically and setups your device for your account. For IoT developers, you can obtain your devices API keys for building your management system.Works with IFTTT and integrates into smart-home setups (tested with Wink Hub 2, Wemo devices).CONS (To be honest, not really cons, just things to be aware of. This really is a great product.)I did find the picture of the external temperature sensor (DS18B20) with the product a little misleading. And yes, you have to read below the picture to realize it was an option. If you are a picture shopper like me, then you may miss that. I was expecting an external sensor to come with the device, but was mistaken.(More of a disclaimer, not a con) For people that us English system of measurements, the Ubibot alert rule values are in metric only. However, if you use IFTTT to monitor readings, then you can use that to adjust your threshold values in English units.If you are a developer and need faster data frequency readings, then you are limited to 1 minute device recording, and then the speed of you network to get the data to external data servers. Fastest data frequency is 1 minute.

My application was outdoor temperature monitoring at our vacation home. I wanted a device that I could leave outside in a protected, dry place, and sense tempeatures - connected to the house WiFi, that I could monitor via my mobile phone. When it was connected to my router, it worked great, but the challenenge is that over time, it would drop connection more frequently and for extended periods of time. I even replaced my WiFi router thinking that was the problem, but to no avail. Their tech support team was very responsive and helpful, but at the end of the day, they said that the device was in a high humidity environment which would affect operation. Given that it's a temperature and humidity sensor, that didn't seem like a good response. Plus, I had the device in a ziplock back, in a covered/dry place. Overall, I am very dissappointed, and ended up buying a WiFi sendor from another company.

With no previous reviews to consider, I took a chance on this relatively new product and am glad I did. As a consumer, I needed to monitor humidity and temperature levels in my basement. I'm frequently away from home, and the possibility of the dehumidifier failing for any period of time can have dire consequences for mold in the South.This UK company is clearly geared towards manufacturing and agricultural applications, but for my limited consumer purpose it has turn out exceptionally well. Set-up was a bit of a challenge, but changing to a different home SSID solved that issue. The device capably joins my IoT (Internet of Things) collection of smoke alarms, thermostats and light switches, and I'm now able to monitor the basement levels from anywhere.The computer-based application works well with easy-to-read charts and customizable reports. "Rules" can be set up to send alerts via email such as humidity levels reaching a certain level or the device shutting down. I tested that feature out, and it worked perfectly. The phone app is cluttered and not well-customizable (for example, Cº instead of Fº which is reported out on the computer app), but a responsive support team tells me improvements in that app are due shortly.I can see a great future for this company and its devices for large-scale industry, and for my consumer home-based need of simply monitoring remote humidity/temperature readings, this does the trick. I recommend it to anyone looking for cost-effective and efficient remote monitoring.

Works well, keeps me informed at all times so there are no negatives with this product thus far.

To monitor the temperature of an important freezer for our business. I needed it to work wirelessly as I live some distance from the freezer. I am very happy with the way it works and how easy it was to setup. The app and alarm features are great!
