Hardware requirements and supported devices
Requirements
- Home Assistant Operating System (HA OS) or Docker (Linux host only) for running the TOMMY server
- Minimum 2 devices per zone (same Wi-Fi band - either 2.4GHz or 5GHz)
- Network access - The TOMMY server and all devices must be on the same network and able to communicate with each other. The TOMMY server also requires internet access to communicate with the license server.
Supported Devices
- ESP32 (2.4GHz)
- ESP32-C3 (2.4GHz)
- ESP32-C5 (2.4GHz & 5GHz)
- ESP32-C6 (2.4GHz)
- ESP32-S2 (2.4GHz)
- ESP32-S3 (2.4GHz)
Special Note for Mesh Networks
If using mesh networks, devices in each zone must be on the same access point. Different zones can use different access points.
To ensure devices connect to the correct access point, you must provide the router BSSID (MAC address) during flashing. See the TOMMY Flasher or ESPHome documentation for instructions on how to configure BSSID.
