blynk-pzem-004t-v3.0-multiple-device's Issues

I cant get it to work

1st Issue:
Not able to compile
error: SimpleTimer.h: No such file or directory

2nd Issue:
I comment out the SimpleTimer.h and successfully compiled but I am not able to read anything. Is that necessarily to uncomment SimpleTimer.h?

I am using Arduino 1.8.10.

====================================================
Now checking Modbus 1
Failed to read modbus 1

Now checking Modbus 2
Failed to read modbus 2

Not able to read anything from the D5 and D6. I tried other pin D1 D2 and TX RX also cannot. Tried to swap to a new ESP8266, still remain the same. I tried example given PZEM

The current power and energy have 32 bit register with "nodeX.getResponseBuffer(0xXX)" can read only 16 bit is correct?
I think it looking the energy counter some time restart from 0 after have count 66.
