The sonoff 4ch doesn&rsquo;t allow 230V inputs! :(</p> <p>I was really upset at the beginning, but then I took the solderer and solved the problem, as always ;)</p> <h2 id="enabling-external-buttons">Enabling external buttons</h2> <p>I took some spare cat5 inside cables and solder the line and ground of the buttons.</p> https://lorenzo.farnararo.it/en/posts/flashing_esphome_shelly_1_with_arduino_uno/ Thu, 22 Dec 2022 00:00:00 +0000 https://lorenzo.farnararo.it/en/posts/flashing_esphome_shelly_1_with_arduino_uno/ <p>I recently got a Shelly 1 v3 wifi relay, and I had already decided I did not want to use the Shelly ecosystem but to connect it directly to Home Assistant via ESPHome.</p> <p>The Shelly 1 relay offers header pins to connect to, for debugging or flashing. Connecting it to a computer requires an USB/TTL converter.</p> <p>You can either buy it on amazon for cheap, or luckily if you have an Arduino laying around, you can use it as an USB/TTL converter easily!</p>
