Wow super

[@bhagyeshgunda9501]

Even after running the code I am getting an error in the 39th line which is telling me to specify the template ID and name. But I have verified it several times and it's always correct idk why it's showing error

[@Dehcjemkeihhehu3709]

How can we get the code?

@@Elextrolyte In code you set relayPin = D0 but in the vdo, u r showing to connect relay IN with esp8266 D1
