Excellent DIY and Pro home alarm kit. Not is it just great hardware, but unlike many others on the market they have a great app that works reliably and have an excellent support team. No issue has been too small or too big and they have always resolved all issues. Firmware/features are always being upgraded. Was an early adopter, after wanting to change the home alarm system from a traditional/SMS based system. After research settled on Somfy, however, was a great disappointment so was nervous when investing into a new startup but have not regretted it one bit, no false alarms, accurate status of sensors, no disconnecting sensors, just a stable reliable system, as it should be. Only wish was for a mains powered siren so that i wouldn't have to get the ladder out to change the batteries every couple of years.
