Welcome to GSM-Start, a part of Pierr Automatik AB, a small manufacturer of remote controlled GSM relays and switches in Halmstad, Halland, Sweden. Our units make it possible to control your electrical appliances at a distance with the use of a mobile or a landline phone via SMS, phone calls or our iPhone and Android app, great for remote control of heating, gates or lights. It's also possible to connect the units to a sensor or alarm so the unit will send a SMS when the input is triggered. We develop and manufacture all our remote controlled relays and switches in Sweden using only high end components. Since we design, program and manufacture all of our devices ourselves we are more than happy to help you with any custom or OEM.
