core: 0.108.0 WLED causing strange LED strip behaviour
The problem
Before 0.108.0 i was very happily using the WLED integration on 2 LED strips. With 0.108.0 both strips (both with their own, and different, 8266 (NodeMCU/Wemos, both running the latest stable release of WLED) now when switched on flash and are unreachable, like something is flooding the 8266? When i delete the integration from HA and restart HA, turn on power on the LED strips, the normal WLED web UI is useable normally. So pretty sure it is HA that is causing this somehow…

I see 2 different issues mixing up here.
The Flashing of the WLED strip after the upgrade, I’ve seen that happen during development once, on a single WLED light. I’ve not been able to reproduce it again ever since. Hence, I ignored it original development as a glitch.
The upgraded WLED integration in 0.108, uses other API calls, which are lighter and faster. How it can cause a crash, is unknown to me. Honestly, the device should not be able to crash by an API call IMHO.
Another reported issue is the timeout issues. The timeout has been lowered in 0.108, to allow faster updates of the WLED state. Looking at the reports here and upstream, I guess it makes sense to revert that part. However, the slowness of response is generally the result of a weak WiFi connection or other network issues.
I’m seeing this behavior on WLED 0.9.1, and I’m not even running HA.
