Install Tasmota on the Sonoff Basic and confirm it is functional before connecting the PZEM-004T to its serial interface.
## Hardware connections
-As the PZEM-004T expects 5V serial data and the Sonoff Basic only provides up to 3V3 the expected optocoupler input power of the PZEM-004T has to be reduced. This can be accomplished by soldering a 1k resistor between the joints shown below (modification works for version v.1.0 and v.3.0).
