Espclicker is a small device that you can use to integrate not IoT devices into your smart home setup, It connects directly to the push buttons of the device, which you want to control, and then simulates pressing them. You can simulate button clicks, hold time, and multiple clicks. Espclicker has three small relays One of which can be configured as normally open or normally closed. also, it has a contactless AC power detector and two “low-side” switches, for connecting additional power relays, so you can connect external relays with different coil ratings, for controlling the big load.
