Wifi SSID and password ( blank)should be the same if you are using a wokwi simulator...

this is version issue ...

what details You want ?? You have to create your Thingspeak account and add your api key and channel number to code.

Yes.. We can send messages on WhatsApp, if the threshold limit crossed. You just have to apply the condition.

@@ThinkIOT I tried to much but I couldnt because I dont know how to define mqtt value in function node
