Dear PICList, We just released a firmware update (v2.2.1 RC1) which adds new voltage-base= d sleep and wakeup triggers: * Voltage level sleep * Voltage level wakeup * Voltage change wakeup The new triggers can be configured to put the device to sleep when the engine is shut off, and wake it up on engine startup. This release is not public; you can download it from the following link: http://www.scantool.net/scantool/downloads/105/obdlink-2.2.1.zip The new triggers are described in the updated PowerSave specification: http://www.scantool.net/scantool/downloads/79/stn11xx-powersave.pdf Your comments are greatly appreciated.
