Having to purchase a New Access hub really upsets my customers - probably blaming me for they're having to upgrade. I run a business monitoring houses in Fairbanks, Alaska in the winter - keeping houses from freezing (we can hit -60 or colder here - it doesn't take long to freeze a house). I used to use the FreezeAlarm, but the AcuRite system appeared to be the way to go - check the temperatures at each customers in a matter of a minute or two any time of the day without having to call the unit to check the temperature. So I had my customers switch to AcuRite, one within the last 6 months. Worked great, a few minor problems but fixed right away. Now my customers must upgrade a system they paid good money for. Plus one customer uses 10 sensors in two houses next to each other with one hub. So more programming, more units, more hassels. Plus now they will have to pay me to program their new Access unit/s. I am totally disappointed and disgusted in the way AcuRite are treating their customers. I may have lost my customers. In a small town like this - bad reputations travel very fast.
