Broadlink SP4M-US Integration

[spencerthayer]

The problem

The problem is that the Broadlink SP4M-US use FastCon™ Bridging which is just a proprietary mesh network for Broadlink devices. According to Broadlink's documentation FastCon works as follows.

BroadLink 4th gen smart plugs support FastCon™ Bridging which allows
devices building their own sub networks with one of them acting as
master and others as clients to minimize the connection load of Wi-Fi
router. When the device was added in the network. It will look for
better network routes in 1-2 minutes and may join a sub network.

This causes issues with the existing Homeassistant integration since we cannot access the switches via their IP address. The following forum posts go into greater detail.

• Anyone get Broadlink SP4M-US WiFi Smart Plug Working? Locally?
• Broadlink SP4M-US Smart Plug - Filling Log with Network Timeout Errors

Is it, or could it be possible, to access and control the SP4M-US over the FastCon "sub network" via the device MAC address? It is worth noting that for all users at least one SP4M-US, functioning as the hub for FastCon, does connect to Homeassistant.

Additional information

The advised hack were users disconnect the each SP4M-US from the internet via the router to prevent FastCon does not work for the latest SP4M-US firmware and as of this posting there is no existing work around.

@Danielhiversen, @felipediel, and/or @L-I-Am I do not believe this ticket warrants being closed since the problem is still persistent.
