Added this sample code from HA: relay control through uart, with some data and need disable logger: Why is Python running my module when I import it, and how do I stop it? Alternatively, if they are high-trigger you can add external pull-down resistors. Since its likely that you will want to switch/power things that are of higher voltage than the 5v rail you need to power the Wemos, Ive included the 12v and 24v optional power supplies. Thanks, BobT: officially GPIOs are only supporting 3.3V (https://www.wemos.cc/en/latest/d1/d1_mini.html), The Espressif ESP8266 datasheet, on page 19 defines also 3.6v and 12mA max current: https://www.espressif.com/sites/default/files/documentation/0a-esp8266ex_datasheet_en.pdf. turn_on_action: Im using the following config for lovelace: This provides you with a simple switch list.
