Product review (2 stars): Not for snowbirds. Requires too much bandwidth. Poor support.
I really wanted this to work. It was easy to set up. I had no problem registering at the web site and setting up triggers. It was easy to go view sensor history, etc. on the web site. But triggering of emails and texts did not work. It is supposed to contact you when the temperature range is exceeded.

I reported this and 2 days later got an automated response telling me the problem report was being closed. So I submitted the bug report again. 2 days later it was automatically closed again. I did call and talked to someone in support, who promised me that they would determine the problem and would keep the bug report open.

After another email exchange with tech support a month later, and with no resolution to the lack of triggered alerts, I gave up. But I could still go to the web site daily and check status -- which was great, though not optimal.

Then, I reduced my Time Warner Internet service to a maintenance level (aka "Everyday Low Price") for the season and suddenly everything stopped working. AcuRite pointed at TW as the culprit, claiming insufficient bandwidth. TW claimed that they could ping my modem and I was getting the required 1 Mb of upload speed, but I was no longer there to verify it.

The upshot is that I'd have to pay $50 a month to TW to get more than 1 Mb of upload bandwidth to make this work. I could get a security service for less than that. So the great experiment failed.

I'm now trying the MarCell product, which is cellular based, rather than internet based. So far so good, but it requires $100 per year for cell service -- not ideal, but cheaper than $50 per month for Internet.
