Gentlemen, My UPS (APC Back-UPS ES 650 FW:818.w1.D USB FW:w1), does provide the UPS variables Voltage, ConfigVoltage, RemainingCapacity, and RunTimeToEmpty both under PowerSummary and Battery. In the current version of apc-hid.h the PowerSummary version of these variables are assigned to the appropriate (I hope) nut variables, except for ConfigVoltage, in which case the Battery version is used. Note BTW that RemainingCapacityLimit is only available under PowerSummary. Would it be recommended to add the four other entries to apc-hid.h, and if so, for which variables should the PowerSummary or the Battery forms come first (i.e. which should be preferred)? As fas as I understand the situation, adding these variables will not provide me with anything new, but it could potentially provide more information for other APC devices. Some advice on this would be appreciated. Thanks, AG -- ---------------------------------------------------------------------- Alfred Ganz alfred-ganz@agci.com AG Consulting, Inc.
