Hey there - I've reviewed your changes - here's some feedback:
- In IkaNamurClient.send(), the loop condition
while time.time() < end or self._ser.in_waitingcould spin indefinitely if the port always shows pending bytes; consider switching to an AND condition or adding a secondary timeout to guarantee exit. - The HeaterStirrer_IKA.temp property returns the setpoint rather than an actual reading; either implement a real NAMUR query for current temperature or clearly document that it only reflects the target.
- Defaulting to a random UUID in serial_node.py on each init may break stable device identity across restarts; consider requiring a consistent device_uuid injection or persisting it externally.

## Overall Comments
- In IkaNamurClient.send(), the loop condition `while time.time() < end or self._ser.in_waiting` could spin indefinitely if the port always shows pending bytes; consider switching to an AND condition or adding a secondary timeout to guarantee exit.

**suggestion:** Using asyncio.to_thread for synchronous serial calls is appropriate, but error handling is minimal.
Add exception handling for errors during serial communication to improve robustness.

- Lift code into else after jump in control flow ([`reintroduce-else`](https://docs.sourcery.ai/Reference/Default-Rules/refactorings/reintroduce-else/))
- Replace if statement with if expression ([`assign-if-exp`](https://docs.sourcery.ai/Reference/Default-Rules/refactorings/assign-if-exp/))
