Your 4-in-1 Sensor 700 series can be updated via OTA firmware updates but most of the 500 series model also underwent hardware changes that make it impossible to update to a newer version. Please check your model and version carefully before updating it. You can access all firmware files here after you register your product and create an account here. Questions? Just reach out to our tech support team.
