  • Fantastic system for electric baseboard heating. Easy install. Easy connection. Easy programming

    from Burnaby, BC on November 4, 2018

    Previously had purchased a Dimplex Connex system and spent 2 days installing, uninstalling and re-installing then attempting to get devices to connect and program. After finally giving up I took that set back and purchased the Sinope basic set. All i can say is WOW! What a difference. It was much easier to install and what can I say it worked the very first try. Follow the instructions and you're good to go. The only thing I had difficulty with was finding my device in the web interface. Once I found that i was golden. So easy to program a schedule and to copy one day program to the rest of the week. So easy to pair. Just works like you hope it would. I highly recommend this set up. Hopefully Sinope will start selling some electric baseboard heaters that have the ability to pair built in.

  • Insufficient information

    from Haliburton, ON on January 3, 2017

    I was really looking forward to trying this product but alas the description of the product is insufficient. if you need 3000 actually means 3000 Watts 4000 means 4000 watts , since I have 4250 W in one circuit I was unable to use this device. so therefore giving it a rating one way or the other would be pretty difficult. very disappointed

  • Great web programmable Thermostat and excellent customer support.

    from Pointe-claire, QC on December 4, 2016

    I purchased the starter kit GT125 a month ago. I had an issue with the GT125 and contacted Sinope customer support. I was amazed with their quick response and follow up. They quickly sent me a replacement item. Now, it works like a charm. Very easy to connect and set-up. I like the fact that you can easily program the thermostat with a phone or a tablet connected to a WiFi. With a WiFi connection, you can view and adjust the temperature of each programmed rooms remotely. Also, once your account is set-up, you can track your heating consumption cost detailed on a graphical data. Overall, it's a great product with excellent customer support. Highly recommended!
