I have a projector screen at church that has been in place for a number of years. I have no information on it other than the up-down is controlled by a 3-position rocker switch, down-off-up. I know that it has 120v at the switch. The switch is in a rather inconvenient place so I would like to automate it. I’m looking for a Z-Wave switch or some other kind of switch that I could use to control this. I thought about doing it with two relays but my fear is that both relays coming on at the same time might damage the screen’s motor. I could protect from this in software but not sure how to protect against a stuck relay. Anyway, does anyone know a device that might replace that 3-position rocker switch that would let me tie it into HA? Thanks.
@gentlec did you find a solution for this ?
Same as a garage door you need a dual relay that will trigger up or down and when not active the screen will just be pause like the middle position. Something like this
