I am in Central America for the next 3 months, and have no way of calling customer support. I live in Canada for the other six months and use my smarthub to monitor my house temperatures during the winter that I am not there. I really believe we are being duped. US law mandates that discontinued products be supported for 10 years after a product or service is discontinued. That being said, this upgrade, for me ends up costing me additional shipping, customs duties, and taxes and when converted to CDN $ it ends up costing me over $80.00. I addition, I can't even access the upgrade link, here in |Central America. And if I could order the upgrade there is no one home to receive shipment. My smarhub functions exactly as expected and does everything I need it do, so an upgrade for me is totally unnecessary and only serves to make it easier for acurite to switch, with the added bonus of selling thousands of units of new hardware. This is total ****** surprised no one has started a class action law suit. I need to be able to email customer support!
