I have a Color Controller in my motorhome and want to show the state of my tanks on the display. This has been a lot more difficult to figure out that I thought it should be.
Now as you can imagine, I don't want to spend $800 on the resistive tank level adapter, and even then I couldn't figure out what devices to buy to make it work. (It would be cheaper to by a Venus! Why are the adapters so expensive?!)
However I do have a raspberry Pi and could easily program it to tell the CC what the current levels are via an API or Modbus. I couldn't see how to change the values, or even make the tank levels show on the screen. It looks like on Modbus the values are read only.
My feature request is:
- Make it easy to set the values of the tank levels via an API (preferably), SSH command line or Modbus.
Or let me know if this is already possible, but I simply missed it.
I'd also like to see clear instructions on what products to buy for to make it work. Which senders work, what type of senders, which adapters needed for the CC etc. I asked the Victron dealers here in NZ but they didn't know anything about it. There also seems to be a disconnect between the language used by Victron (i.e. resistive, voltage or current type senders) and the products sold in NZ. None of which use any of those terms. e.g. https://www.marine-deals.co.nz/ultrasonic-tank-sender or http://www.rvsupplies.co.nz/products/view/electronic-tank-probe-290300
Any help welcome!
