Room Alert12SR Proactive Secure Environment Monitor Foundation Bundle - Supports HTTPS, TLS and SNMP v3, External Temp/Humidity Sensor Included

There are some gotchas here, the unit works fine but it is severely underpowered, if you choose to enable both TLS for email sending and HTTPS for web GUI management. Which any modern company will require. The unit will become burdened to the point where allowing a 15 minute poll recovery time to not alert is not adequate, a 30 minute recovery time seems to be working for the specific alert that monitors from the web that tells you if the local device is offline. The monitoring account is seriously deceiving, offering 10 users and 25 devices along with 25 alerts for the professional tier. You would think that 25 devices are the end devices, and they are, but the 25 alerts are for the same 25 devices. It isn't 25 devices each with up to 25 alerts each. The 25 alerts are the limiting factor. This means you could monitor the internal temp sensor for all 25 devices (25 alerts) or 3 devices which have 8 sensors each with 8 each corresponding alerts. Also to note, I think you need to subscribe to the professional tier either monthly or the lifetime (one-time fee) to be eligible for any software updates. With some updated hardware and a more realistic monitoring limit I think this solution could be great, it does allot of other things right, the interface is easy to understand. One other thing to note, it appears the sensors could be a bit improved, the amount they are off from each other out of the box is really bad so be prepared to adjust the temp for each probe in the software.
