I bought the hub2,and it can connect wiht xiaomigateway3,

But 4 days ago,this one auto update to 1.0.6_0004.

I found it can't normal connet to xiaomigateway3. 

You should use custom open telnet command

The main pros compared to the previous version are:

new hardware: Dual-Core ARM 1GHz, 128MB DDR3 (nice)

more advanced zigbee chip of the same series (although the old chip was great too)

new bluetooth chip (don't know anything about it)

Dual-Band Wi-Fi (although the old 2.4GHz was stable as well)

Ethernet (for those who like wires)

USB Type-C (it's future)

The hub2 can use rj45,and 5ghz, it is more stable than before.

It has telnet access, so theoretically could be supported in the Xiaomi Gateway 3 integration.

You need make sure that the gateway and ha are in the same domain.

The user is “root”

The command is

{"method":"set_ip_info","params":{"ssid":"\"\"","pswd":"123123 ; passwd -d root; /bin/riu_w 101e 53 3012; telnetd"}}

This is wrong telnet cmd for MMG2.

Use integration master version with empty telnet cmd. The right one is built-in.
