@JacoDeJongh if you use the EM24 that supports the external CTs, then you can build a Venus Pi based meter. We got 100A and 200A CTs from Segen.
We build meters ourselves and connect on Customer WiFi or using USB powered 3G routers off the Pi USB port to log.
We have built 4 so far:
- EM24 External CT Edition EM24DINAV53DISX
- CTs from Segen
- Raspberry Pi 4 or 3B+
- AC to DC USB Power Supply for Pi
- RS485 to USB for EM24 to Pi USB
- SD Card with Victron Venus OS
The only downside is all we get is L1, L2, L3 power and not voltage, current, pf etc as available from the meter.
See other thread about that here: https://energytalk.co.za/t/getting-pf-and-other-details-from-em24
Ps. For internet, we usually use TP-Link MR-3020 powered from Pi USB port with an old skool USB dingle inserted.
