Question 1

SonoffLAN vs Tasmota: which is better for Home Assistant?

Accepted Answer

SonoffLAN is easier since it works with stock firmware and offers dual protocol support, but Tasmota provides more control with local-only operation and custom features. Choose based on whether you value convenience over customization.

Question 2

How to set up SonoffLAN for local-only mode?

Accepted Answer

Set mode to 'local' in the integration UI, but note it requires eWeLink credentials for device keys and may have stability issues. Ensure your network supports multicast, and consider auto mode for better reliability with cloud fallback.

Question 3

Why do my Sonoff devices keep going unavailable in SonoffLAN?

Accepted Answer

This is often due to multicast DNS problems. Check your network setup, avoid NAT in virtual machines, and use the auto mode to leverage cloud connections as a backup, as recommended in the README.

Question 4

Can SonoffLAN work without an internet connection?

Accepted Answer

Yes, in local mode with cached device data, but initial setup requires cloud login to fetch encryption keys. Some sensors, like power monitors, may not update without cloud after 2026.

Question 5

How to configure the Sonoff RF Bridge with SonoffLAN?

Accepted Answer

Use YAML configuration to map RF signals to sensors or buttons, specifying device_class and timeout. Examples in the README show how to handle single-state or dual-state sensors for automation.

Question 6

Is SonoffLAN secure for local control?

Accepted Answer

It uses encryption keys from eWeLink for local communication, but DIY mode is unencrypted. For best security, use auto mode with cloud credentials, and avoid exposing devices on untrusted networks.
