BMW E65/E66 | Webasto control via Secolink App

This work around allows to have control of Webasto heater using external control device, because BMW E65 no longer supports manual Webasto startup when supplying +12V to pin1 in Webasto connector (like in older BMW cars). In this case I have GSM security alarm system installed, together with mobile app control. Advantage over standard Webasto remote control is no distance limit, no need to carry additional remote control. Using the app, over GSM startup signal is sent to security alarm module, then it activates this additional module (Arduino based), which simulates buttons pressing on remote control. It is possible to start and also stop heating/cooling.
