Ubibot WS1 WiFi Temperature Sensor, Wireless Thermometer Hygrometer, Humidity Monitor, Remote Data Logger with Free App Email Alerts, IFTTT Thermometer,(2.4GHz WiFi only,no hub required)

Bought this to monitor my cryptomining farm as I liked the idea of getting alerts when temperatures got too high so I could shutdown equipment remotely. Note that this has to be combined with a smart plug to actually shut the equipment down. It was so easy to setup (on my old iPhone 5C and iPad 2) and I have added temperature probes and powered all sensors apart from the outside one by USB which means no battery issues. The app is really good compared to others allowing pictures to be downloaded to identify where the device are and a great dashboard where you can see the current status of all devices. A more detailed charts section shows temperature, light, voltage, wifi and humidity graphs over a custom or default time period with min and max values. I have contacted Yang who offered support for when the USB splitter for the device was going to be available and discussed app improvements and he got back to me in a matter of hours. I am looking forward to future minor app updates to make this even better. A great device for remote monitoring which is better than anything else I saw available and has not disappointed. I have several of these devices now inside and outside the house (with protective cover) and am very pleased with the results.

I used this to monitor temp over winter in an empty house. Easy to set up, connecting with home wifi. Occasionally has drop outs but that's the modem, not this unit. Unobtrusive, batteries still going after several months. Also has light and movement measuring though not so useful. Could be used in numerous locations for measurement. Good pc/phone app interface. Multiple units can be used on one account. Recommended.

This little device packs a lot of features although I only need it for temperature and humidity. Setup was straightforward and I was online with the UbiBot Cloud free service in no time. One thing to remember, and the FAQs on this device do point out is the initial setup generates heat so it will take a few minutes for this to settle and for the ambient reading to then start to appear. I had a minor issue with my device to do with the batteries draining quicker than normal. Yang at UbiBot support could not have been more helpful and diagnosed the problem quickly and replaced the unit without fuss. Excellent customer service when I needed it most over and above the fact that the device itself is superb. I look forward to being able to integrate with IFTTT to help trigger smart plug actions to switch on/off my radiator. UPDATE: IFTTT integration now available and it works like a dream - if the UbiBot sensor detects my room temperature is above a set range, instead of just alerting me it now turns off my Meross Smartplug. Similarly if the sensor detects the temperature has fallen below a threshold it can switch my smart plug on. This was the missing link for me and now that its here it makes the device indispensable in helping me mange the temp/humidity without a need to physically be in the room to switch devices off and on. The heater itself has a thermostat but there are no numbers on the dial so I am always guessing. This way I can have a variety of applets for a variety of use cases such as just keeping the cold and dampness away whilst I'm not in the room for an extended period of time or applets that work for me whilst in the room.

I got a 2nd device which was listed as WS-1 but is in fact a WS-1A which is a cheaper cut down version of the original sensor, it is missing knock and vibration sensors as a minumum, not sure yet what other differences Original review for WS-1 (not 'A' model) I have this device to give me telemetry from my pump house (private water supply). While not cheap the device is packed full of features, more than I realised when I bought it, so as well as temperature (which is what I needed) I also have light levels and a knock sensor which is potentially handy for me. Another great feature of the device is that it uses USB and/or battery power, so I have it plugged in but in the event of a power cut it will still take readings albeit that it can't send them until the power is restored to the wifi the device is setup for. Another handy feature is the ability to setup triggers on the website or mobile app, so I can set it for example if the pump is running too hot or if the sensor stops sending readings (wifi down)

What an amazing little device. I have set up a VPN connection on a 4G router which sits in my boat. I needed something which I could use to monitor temperature and humidity remotely whilst the boat is unoccupied. The WS1 fits the bill perfectly as it samples and logs the readings internally and only uses the Wi-Fi for brief synchronisation every 15 mins (configurable). I am using a couple of rechargeable batteries for power and it's too soon to check how long they will last but likely several months. You also get vibration and knock sensor readings which could be useful to detect storms etc. I'm just using the free UbiBot IOT cloud for monitoring ATM but you can sign up as a developer and interface directly to the device via their open API. All in all, everything I would want for a monitoring device. The only sight negative is that the case seems a little flimsy and the device is not really suitable for very wet environments but UbiBot are up front about this in the advertising. Very Impressed!

Very good app, unit was a little bit fiddly to setup for me as i had to use a WiFi extender. If you are planning on using this unit a little away from WiFi check with your phone to see what signal strength is at that distance first. 1 or 2 bars WiFi and the unit will drop off and keep putting up notifications, I've only had one 15min drop out after a week of using WiFi extender so all is good. Loads of information on the app and the ability to set notifications for light, temp, humidity etc is a really good option.

Had three and after a few days stopped working they worked well on battery but when used with usb they stopped working they were returned and had a full refund I'm pleased with amazon had no problems return ing them

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. PROS Now 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.

El equipo funciona bien y la app es bastante buena, pusexelfequipo en un site y si me sorta si se enfría o se caliento demasiado muy bueno para el precio

I bought this for monitoring our home in the winter while we were away. I'm not a techy person so I asked my highly techy nephew to check it out for me. He said it was a good deal because most companies require a yearly fee for data and the amount of data included with the UbiBot purchase is enough that we would never use it all. It stays continually connected to the wall using the cord & plug it came with. It has batteries for backup if the power goes out. It worked very well! We tried it out before our trip away by putting it in a cold area that was below the low temperature we had the monitor set at. It worked, sending me an email too and also an alert on my cellphone UbiBot app. It was the first time I wasn't worried about the house when we left it in the winter. Even when we have people checking the house every 2 days there is always a concern that things will freeze up quickly in severe cold weather, so this UbiBot is perfect! I can check the app often from our vacation spot using the app. It shows when the temperature started to decline if it happened. I'm very pleased. I needed my nephew to help me with the initial setup in connecting the app with the device, because, as I stated, I'm not a techy person....any set up directions seem too complicated for me. Once it is set up it is easy to use to monitor your temperature, humidity, light and vibration. I just use it for room temperature.
