Everything is done ok .3 Devices are seen on sinic pro and in alexa and google home successfully linked but it reports devices un responsive both in Alexa or Google home. they are always shown as device is offline in sinric pro, alexa and google home. It does not show the wifi connected on the serial monitor but Wifi LED blinks in regular intervals on the NodeMCU that I use of version 3 from LoLin. The same NodeMcu but worked perfectly on your Blynk code showing wifi connected..

can you tell me what the 4 edge hole is called and what is the purpose of its? I want to screw it in pcb instead of soldering it using that 4 holes. is it feasible? please reply

[@er.kunalbhadane6466]

No

[@arghyaghosh1156]

The problem with your design is that the physical switch state wont change if you turn on from switch and turn off from alexa. It would be better to use push or touch buttons here. You van also try adding in a raspberry pi with home assistant to add a cluster of such nodemcu subsystem in the entire house

[@inkits1]

I agree to this suggestion. Could you use maybe even STM 32 or R. pie to control the whole house with cluster of switches .

[@kapilverma_brutecoder]

And increase cost 10 times with Raspberry Pi , very good suggestion.

[@tariq4846]

Can we do project with relay, nodemcu and switches only and removing transistors, resistors, etc as it needs electronic knowledge

[@sampathkumarspace9162]

Giving switching control with nodemcu had lot of mal function. Relay Automatically turns on or off if some switch turns on from other room which means does not has physically connection to nodemcu Junction. Sometime can't able to communicate with nodemcu needs to restart complete. It's really difficult to remove from Junction and reset. Note : you can't find these issues with demo session , you need to test real-time which means need to connect in home switch board or Junction and where you using regularly.
