Hi, just wanna give my contribution to the community.
Following is the serial gateway code with support of auto ID, which is still missing in the latest of MySensor (1.4) library (CMIIW).
Just for completeness: the right way to do this is to add the json under ~/.platformio/boards and the other files as described in https://community.platformio.org/t/how-use-a-same-chip-but-with-different-environment/18082/4
@OldSurferDude well, the ESP8266 is limited to 4 TCP clients in arduino IDE. This can't be really increased. I did som experiments and you can set it up to 15, but after the 5th client on my web server, I got a freeze.
Maybe you got something wrong. #define MY_GATEWAY_MAX_CLIENTS 2 defines how many controllers (eg Home Assistant) can connect to the gateway, not how many sensors/MySensors devices.
And yes, you can have multiple TCP gateways in HomeAssistant. I got an NRF24, an RFM95 long range and a RFM95 short range gateway (all based on ESP32) on the same Home Assistant.
