Thing.handle() is not updating all 'Thing's value

I am trying to integrate Arduino Mega with multiple sensors and output devices (as Slave) and NodeMCU cloud transceiver (as Master) to the cloud. I have succeeded to stream sensors log but for some reason, some things are not being invoked on respective conditions. On the serial monitor, I can confirm that they are not being invoked by thing.handle(). Is there a way to invoke a thing manually or to define/configure execution sequence of thing.handle() or perhaps some simple fix. Kindly give me some insight on this issue.

Thankyou
