Multi-function stairlift connectivity system
Multi-function stairlift connectivity includes a stairlift data collection system having data collection devices communicatively connected to a main controller. Such data collection devices may include sensors, switches, controllers, detectors, control boards, and location detectors providing data and settings in a stairlift (e.g., diagnostic information, system status data, faults, drive performance data). A communication module receives collected stairlift data and communicates wirelessly with a remote communication device. Waypoint detection may include stairlift carriage position detection employing electrical contacts on a stairlift carriage. Carriage position can be determined when the carriage stops at or passes a waypoint marker that includes electrical contacts connected to a waypoint element possessing a detectable electromagnetic characteristic (e.g., an identifiable resistive value). Where resistive value are used, waypoint locations can be determined by using a different resistive value for each waypoint.
