Proteus Wifi Temperature Humidity Sensor with Buzzer and Email or Text Alerts

My old freezer failed twice, losing all my food. Never again! This thing is amazing. No special apps (can still easily set up with phone), informs of wifi or power outages, can set notification thresholds for temp and humidity, text + email alerts, and a loud alarm (which you can deactivate of desired). Worth every penny.Tip: for freezers, get a USB extension cord to run through the door opening. It will be too thick for the door to seal, so strip the outer insulation, leaving the insulation on the wires inside. Flatten those out going through the door. Secure with duct tape (or gaffers tape, if concerned with residue). Then build up around it slightly with duct tape (just enough to smooth the bump) so the door seals without gaps. Or if you have an older/cheap freezer (mine was brand new), drill a hole somewhere safe, run wire, then fill with spray foam. Follow these tips at your own risk (shorting wires can cause fire, drilling through freezer can be hazardous).

Put this in a small computer room to monitor temps just to make sure cooling system is on the job. Added bonus, good for monitoring power and WiFi failures. Setup was pretty easy, used smartphone WiFi to initially connect to it to get it to connect to the building's own WiFi, and from there setup a Proteus cloud account. It all took just a few minutes (even with having to authorize the device's MAC on our WiFi system). Decent range of 5 different logging options from 1min increments X 24 hrs up to 30min increments by 30 days. Changes to the cloud settings update to the device pretty quickly, like changes to alarm settings. Setting up text and email alerts were also easy and work well (for text alerts, your provider needs to support SMS email gateway, most like Rogers, Bell, Telus and others do but whether your individual plan allows it would be the question). The alerts originate from the cloud service, so if the local network goes down the power/WiFi fail alert can still be sent. There are 3 kinds of alerts possible, temperature, humidity, and power/WiFi fail. The device has a beeper when an alarm goes off. It's fairly loud and can be heard even several rooms away with doors closed. There are more advanced notification and logging options but I think this requires a paid upgrade to the account (longer more detailed logs, Alexa and IFTTT, etc). The included logging and notifications are more than good enough for me.

Really easy to set up. Needs a WiFi connection so - just as with other smart devices it creates it's own WiFi network that you connect to for setup.You then set up a free account on their website and configure the temperature and humidity thresholds.We have it in our server room and it is tested and working fine.Can send alert emails to multiple email addresses.Alarm is quite loud which is great.Much smaller than it appears in the pictures.Thankfully no explosions as suggested in another review. Don't let that deter you.No more overheating servers when the Air Con goes off.All set up within 20 minutes.

Zuverlässiger Überwacher. Wir verwenden es um bei Abwesenheit über einen Heizungsausfall informiert zu werden.

A very simple piece of tech, that is equally simple to use.Can not recommend highly enough.
