Serial Monitor overflowing with "Got characteristic X.XX change event"

[seamaster101]

I'm getting serial monitor overflowing with the following data every time I open the application on my iPhone:

---

HomeKit: [Client 1073688948] Got characteristic 1.10 change event HomeKit: [Client 1073688948] Got characteristic 1.13 change event HomeKit: [Client 1073688948] Got characteristic 1.10 change event HomeKit: [Client 1073688948] Got characteristic 1.13 change event HomeKit: [Client 1073688948] Got characteristic 1.10 change event HomeKit: [Client 1073688948] Got characteristic 1.13 change event HomeKit: [Client 1073688948] Got characteristic 1.10 change event

---

and that repeats for long time even I I close the application (maybe still displays what's in the buffer?) then after some time there the following error:

---

HomeKit: [Client 1073697900] Got characteristic 1.10 change event HomeKit: [Client 1073697900] Got characteristic 1.13 change event !!!

you have my sketch in #2. it happens even if I remove the second sensor and use only temperature sensor the application appears to work OK, but there is definitely something going wrong for that much chatter on the serial monitor... Please help

I ordered DHT11 for testing, it's on the way to me, In my experience of usage BME280 (my preferbale device) I have sent notification to Apple only if difference between new value and old value For instance HOMEKIT_CHARACTERISTIC_CURRENT_TEMPERATURE); if(ch1->value.float_value!=temp} ///validate if temp is changed ch1->value.float_value=temp; homekit_characteristic_notify(ch1,ch1->value); delay(10); }

The same for humidity

You can see my usage in https://github.com/Yurik72/ESPHomeController

It litle bit complex

Yes, this helped! No more chatter on the serial monitor. You can close that one too. It works perfectly well now with DHT11!

Hi, please send me the latest version of your sketch, i will put into examples as well The problem was that is too fast updating apple... After applying my solution, Apple home is not updating such frequently, but potentially it can be. The final solution is to increase a measurement time or/and compare values with some delta before sending to Apple. I suppose is enough for such purpose . It's only "user" monitor and not so important to see values with couple of second of delay or with decreasing of accuracy.. Any how i continue working on library to prevent this "user" usage in such manner and increasing stability on the core
