Hi,
Here is the code bellow.
I think the server is sending the http request but i see in the logs that somethimes it didn't get a answer.
So maybe ESP is busy with something else or is not reachable.
I don't know if the server didn't get a answer if it send the request again and again,flooding the esp, that may be the cause of the crash.
i saw on youtube someone using MQTT, is it more reliable than HTTP to send request to esp ?
the idea is to play a neopixel effect until the domticz server send a new request for a new effect, i have some loops, these can be the issue also, what do you think ?
