ID: 5082 Title: gude_powerbanks: Adapted discovery of powerbanks Component: Checks & agents Level: 1 Class: Bug fix Version: 1.5.0i1 Devices with OID_END=38 are 12 port power switches with two powerbanks. Means each powerbank has 6 outlets. Here we can use ChanStatus in order to find out if one powerbank is enabled/used. Devices with OID_END=19 are simple switch outlets: 1 Port and 1 powerbank Once it's plugged in, the state is "on". Thus we use PortState in discovering function.
