wooly Posted November 6 Posted November 6 A version of shelly 2PM, mostri for use with covers, that works at 24 or 12 VDC and can supply 0 or 12/24 V on each of the exit, [two SPDT relays or four transistors] actually allowing to drive a DC motor where direction is given by the polarity. Being DC current [useful for calibration] could be read with a 0,05Ω resistor, need redesign of board, but would use same software and interface. Quote Translate Revert translation?

wimb Posted November 7 Posted November 7 (edited) They can make an interface board with 2 relays, a resistor, a terminal strip and a connector to put in a Shelly UNI plus. With some scripting or a special firmware it will work. Only the housing can be a problem. No way to put it behind a switch. Edited November 7 by wimb 1 Quote Translate Revert translation?
