Hi! I’d like to know the difference between these two system configurations. So far, they look the same to me, but I’d like to know what are the advantages/disadvantages of ditching the base station and opt for the WiFi option.

Thank you in advance!!

EmonBase is usually referred to as being an RFP69Pi card on a RaspberryPi so the EmonTX and EmonBase communicate via RFM.

A third option is an EmonTX wired directly to an RPi.

  1. EmonTX → RFM → EmonBase (Emoncms on EmonBase)
  2. EmonTX → EmonESP → WiFi → Emoncms
  3. EmonTX → Serial/wired → RPi (Emoncms on RPi)

The difference is how you then host or manage the data from the EmonTX. With option 2 you need another device somewhere hosting Emoncms or just use emoncms.org.

Option 3 is the cheapest, but needs some user effort to do the wiring. If you search the forum, you will find several options for the serial connected version.
