Describe the bug
Setting up the integration fails during async_setup_entry. The device model string is built from registers 111/112, but on my unit register 112 returns an int instead of a str, so " ".join(...) raises a TypeError and the whole config entry setup aborts.
Unit: Zehnder ComfoAir E400
Connection: Modbus TCP via Elfin EW11 gateway (port 502, 19200 baud, 8E1)
Mode: 3-way switch
Traceback
Error setting up entry Zehnder ComfoAir E400 for comfoair
Traceback (most recent call last):
File ".../config_entries.py", line 798, in __async_setup_with_context

model_display = " ".join(p for p in model_parts if p) or None
TypeError: sequence item 1: expected str instance, int found
Cause
In __init__.py:
model_parts = ["ComfoAir", hub.data.get("112"), hub.data.get("111")]
model_display = " ".join(p for p in model_parts if p) or Nonehub.data.get("112") returns an integer on my unit, and str.join() only accepts strings.
Suggested fix
Cast each part to str before joining:
model_display = " ".join(str(p) for p in model_parts if p) or None
Happy to test a patch if useful.
