Im kinda surprised that this hasn’t been spotted before! I’m glad nothing went pop…

see the ‘emonVs questions’ topic (Dec 2023)

emonVS questions

When the emonVS was introduced, it provided voltage sensing and power for the emonTx4 via a 6 pin RJ11 connector at both ends, and power for the emonBase 433Mhz (RFM69SPI) via a USB-C connector Looking at the photos of the emonPi2, it has an 8 pin RJ45 connector for voltage sensing and power; github and Docs confirm this. The github changelog for the emonVS confirms that the voltage sensing and power connector was changed from a RJ11 to a RJ45 at V1.2, and the pinout matches the emonPi2. I’m…

EDIT:

Perhaps there should be some compatibility notes about the emonVs RJ11 (emonTx4) version and the emonVs RJ45 (emonTx5, emonPi2) version in the Docs and on the relevant Shop pages.

It gets a bit complicated as I think there were three? versions of the emonVs RJ11 (emonTx4):

1. single phase including a +5V PSU, with RJ11 (VS1,+5V) and USB-C (+5V) outputs
2. three phase including a +5V PSU, with RJ11 (VS1/2/3,+5V) and USB-C (+5V) outputs
3. single phase not including a +5V PSU, the emonVs RJ11 mini with an RJ11 (VS1) output

Also perhaps some details of converter cable wiring; although I’m not sure how well the RJ11 output on 1) and 2) would run an emonPi2 with just one wire pair for the +5V/GND. The USB-C output could be used for power though.
