Modbus-Rtu 2-way Relay Module Output 2 Channel Switch Input TTL/RS485 Interface Communication $17.99 10pcs Modbus RTU 7-24V Relay Module RS485/TTL 1-way Input and Output with Anti-reverse Protection $49.07 Quote from: Robin2 on Aug 16, 2017, 06:38 pm Maybe you could make another circuit that turns power (or GND) for the opto-isolator with two other separate opto-isolators one each powered and controlled by the Arduino or the Wemos. Also add a current sensor so I can tell if the light is on or off (secondary goal). I was looking for a solution to turn on or off the light using either of my 2 physical switches or eWelink. The “relay” continues to work (i.e., via the physical switch), but they drop off the network and no amount of reset / exclude / include attempts are able to get them working again with SmartThings. There is then no need to detect what state the relay is in. Energizing the relay OR switching the physical switch will turn off the light. Joined Nov 23, 2012 8,012. Throwing the two way switch will invert the state of the relay. I have a problem where on my 3-way switch, the relay wont work. Hi, I couldn’t really find a good schema how to wire a 2-way switch to a shelly1. The signal from the microcontroller is connected to the IN pins, and from there it goes into an optoisolator. V .
