Let me know the details, I'm on a very similar case.

This program is just a helper for protocol reverse engineering, and will only be read-only. There are 7 different types of packets (or telegrams), see https://ibb.co/tXvhKq5

I use a serial to tcp bridge (ser2net). Thus far I've decoded some data in packet type 6 https://imgbb.com/rHhsNVs

My next step is build a esp-home plugin, so I can read the data with an ESP8266 and send it to Home Assitant

Thats fine. But what is the physical layer? Is it a RS485? There is another Toshiba protocol project, but not for Estia. Maybe there are some similarities.

Just RS232 TTL, baudrate 38400 8N1 probably used for estia startup tool (but that is write only)
