Sonoff Dual R3 with ESPHome
In questo articolo analizziamo come caricare il firmware ESPHome su un Sonoff Dual R3. Il modello in analisi è quello che riporta sul PCB la sigla DUALR3-Lite POW e come hardware version la rev 1.x.
GPIO Pinout
| Pin | Function |
| GPIO13 | Status LED (blue / inverted) |
| GPIO0 | Push Button (inverted) |
| GPIO27 | Relay 1 / LED 1 (red) |
| GPIO14 | Relay 2 / LED 2 (red) |
| GPIO32 | Switch 1 (inverted) |
| GPIO33 | Switch 2 (inverted) |
| GPIO25 | Power sensor UART TX |
| GPIO26 | Power sensor UART RX |
Per la misura della potenza gli integrati utilizzati sono il CSE7761 Power Sensor (v1.x) oppure il BL0939 Power Sensor (v2.x)
