AHT10 sensor sends measurement results irregularly


I have a problem, that my AHT10 sensor, which runs via an esp, doesn’t send its measurement results regularly. I declared the update interval as 5 min, but sometimes it sends every 5 min some values, then it won’t send any value for the next two hours. I just can’t figure out why this happens. Is this a common issue?

(My ESP does multiple things which work 24/7, so the issue can’t be the esp I guess? Changing the sensor doesn’t change anything.

Does somebody have a clue how to fix this? Thank you!
