MH-Z19C Measurement Accuracy and Notification

I have a MH-Z19C and want to send a message above 2000ppm, it works quite well. However, I get 30 messages in an hour (especially at night) because the values ​​jump sharply.

Does anyone have experience with this? Do I have to adjust my notification or someone has a good idea how I can solve that not so many messages are sent.
