Hi have recently tested out my Rasperberry Pi running Venus OS to send data to the
Victron cloud portal so I can keep an eye on my 360Ah of Gel batteries/solar when I am away from the
boat.
The Rpi3 is hooked up to a
Victron BMV712
battery monitor and Victron Smart
Solar 100/20.
What a match made in heaven. The information I get is so detailed and it only sends a trickle of data even though its updating every few minutes.
I was initally bit worried about what it would draw as I am powering the raspberry Pi as follows:
1. Rasp Pi 3 (about 3W)
2.
Mikrotik MiniLTE AP (9W)
3.
Victron Pheonix Inverter to
power Rpi and Mikrotik.
Surprisingly this lot only seems to need 1.2-1.4Amps, which is pretty good.
I know what your about to say - use a DC-DC converter to save powering up the
inverter and its more efficient. Well thats exactly my plan...
a. Instead of the router I am going to put a
LTE/GPS hat on the Raspberry Pi from SixFab. This will save me powering up the Router at all (plus it has GPS).
b. I will one of these for the DC-DC conversion :
CTP DC-DC
The residual questions are :
1. Has anyone tried to marinise a Rpi case using silicone?
1a. The other option is Sixfab
waterproof case - anyone tried one?
2. Does the standard Rpi case take Rpi's that have hats on?
3. I haven't been able to get Temperature on my VRM portal. I have two Smart
Battery Sense (Bluetooth) units that show temp on the Smart
Solar but it doesn't come through to VRM portal.
Anyone else running VenusOS on Rpi?
