I love the system, it worked as expected. There was a minor problem with Home ID details but it was easily solved in the software. The freezer monitor works great, will send and alarm if the temp goes above 0 Celsius, yes I would like an alarm reported in the negative side of Celsius but not a big issue. I ordered a tilt sensor and two leak detectors after initial confidence testing . Prices are reasonable, reliability is good. If your a technical person you will have little problems setting this up.
The product was shipped quickly. It is compact and simple to place into service. I did have some initial problems with one of the sensors, however the service from the vendor Michael Phillips was outstanding. He was very responsive to my needs and worked with me until everything worked just fine. He furnished everything needed without any additional expense on my part. I would highly recommend this vendor.
