5 months ago I got it to work by hacking at the code. After some hours of debugging, I could see that hyperHDR is sending the full LED device data and it is overflowing the buffer. I made some changes to hyperhdr/client.py (under hyperhdr-py) by finding a post on google regarding how to read a stream and catch partial read exception. I then forced a second read under json.loads exception to get the full buffer. It is a not a pretty solution, but it got my integration to load and work. Posting it here in case this can help in fixing the code correctly. Technically, this should be posted under https://github.com/mjoshd/hyperhdr-py.
client.py
- add new function
async def _readWithoutLimit(self, stream): sep = b'\n' seplen = len(sep) try: return await stream.readuntil(sep) except asyncio.IncompleteReadError as e: return e.partial except asyncio.LimitOverrunError as e: return await stream.read(e.consumed)
change line 484 to: future_resp = self._readWithoutLimit(self._reader)
line 514, remove "Return None" and replace with: future_resp = self._readWithoutLimit(self._reader) resp = resp + await asyncio.wait_for(future_resp, timeout=timeout_secs)
I also removed the LOGGER.warning (line 510) so it doesn't appear in my home assistant log. This is a not "good" code but works until someone with more knowledge than me can fix it correctly. Unfortunately, I know nothing about asyncio functionality.

Hi,
Hope you can help. Just finished my projector HyperHDR setup with 1172 LEDS. The HyperHDR is working really well but Home Assistant integration doesn't work. I have spent a few hours trying to track down the issue and found that as soon as I define more than 891 LEDs, the integration crashes and can no longer connect. Anything up to 891 LEDS works flawlessly.
I am using Rapsberry PI 5 with HyperHDR 20 beta. The error is HA logs are follows: Traceback (most recent call last): File "/usr/local/lib/python3.11/asyncio/streams.py", line 548, in readline line = await self.readuntil(sep) ^^^^^^^^^^^^^^^^^^^^^^^^^ File "/usr/local/lib/python3.11/asyncio/streams.py", line 626, in readuntil raise exceptions.LimitOverrunError( asyncio.exceptions.LimitOverrunError: Separator is not found, and chunk exceed the limit
During handling of the above exception, another exception occurred:
