Xiaomi Multimode Gateway - compiled MultiPAN RCP firmware (EZSP Firmware: 7.3.1.0 build 0)

[zalatnaicsongor]

Hello,
If it seems to be worthwhile to incorporate into this project, see my repo at https://github.com/zalatnaicsongor/MGLGWFW

Instructions:

• download script.sh to /data/script.sh
• The baud of the multipan RCP firmware is 115200, the EZSP version is "Firmware: 7.3.1.0 build 0"
• Install the Silicon Labs Multiprotocol addon in HA or use a standalone cpcd instance
• execute the script, I tested it on the latest custom version of the firmware.

Home Assistant setup:

• Currently due to some weird bug in the openmiio_agent code, cpcd does not connect through the serial proxy provided by openmiio_agent, to work around the issue, use ser2net /data/ser2net -d -C '7000:raw:0:/dev/ttyS2:115200 8DATABITS NONE 1STOPBIT'
• Note: ser2net is downloaded by the firmware update script
• Configure the Silicon Labs Multiprotocol addon with the following options:

device: /dev/ttyS2
baudrate: "115200"
flow_control: false
autoflash_firmware: false
cpcd_trace: true
otbr_enable: true
otbr_log_level: debug
otbr_firewall: true
network_device: {gatewayIP}:7000
stdout_trace: true

• ZHA should automatically discover the socket created by the multiprotocol addon, for zigbee2mqtt use tcp://core-silabs-multiprotocol:9999
