ESPRoomba

Smartify your iRobot® using an ESP-01S

Features

• Detailed user config file (rename config.h.example to config.h)
• DHCP and Static IP support
• Ability to connect to a specific router using its BSSID (useful on a mesh network)
• OTA Updates
• Communicates over MQTT

• Ability to wake the iRobot® up from normal & deep sleep
• Ability to command the iRobot® to start normal/spot/max cleaning / stop cleaning and go back to the dock
• Ability to set the iRobot®'s clock (automatically (on every restart or every 24 hours) and manually using an MQTT command) with DST support (Needs to be enabled in the config)
• Get a detailed charging status from the iRobot (if the DEBUG option is set to true)
• Ability to guess the iRobot®'s status (the Roomba® Open Interface (OI) doesn't report cleaning status)
• Ability to report more advanced sensors (Battery temperature & voltage, General power usage, Motor currents, the value of the Virtual Wall sensor and which button is being pressed) (if the SENSORS option is set to true)
• Ability to report the full WiFi status (SSID, BSSID, Channel, RSSI and IP) (if the WIFI_DEBUG option is set to true)
• Ability to restart the ESP and the iRobot®
• Ability to power off the iRobot®
• Can be hooked into Home Assistant using only a Template Vacuum configuration
