Review on π ICStation Relay Power Switch Module with Optocoupler - 2PCS | High-Level Trigger | DC 3V 3.3V | For ESP8266 Development Board Arduino by Michael Cooper
Works with known input
Works well - NOTE: For small boards (e.g. ESP8266) you need to supply 3V to V+ and switch separately - the individual pins have no power to switch individually. Let's see how long the season lasts. Use to switch garage door opener via Smartthings and ST_Anything
- Quality construction
- Has flaws
