Hi,
I have a setup with the Cerbo GX, ET112, BMV712 and a Quick 12v battery charger in a boat. I have the ET112 in-line on the shore power to monitor load. No inverter or Victron charger in the setup by now.
On the GX I can see the ET112 and the power passing through it, and it reports itself as grid. Is there any way I can change this to shore and configure an alarm/notification if disconnected?

Hi!
I have tried to find out a way to monitor shore power without replacing my analogue Victron Skylla TG charger. Tried a post on the Victron Community to ask, but nobody has responded. Then I found your post, and it seems like you have found the solution.
Like you I have a Cerbo GX.
Is it possible to install Victron Energy Meter ET112 just after my shore power intake on my Yacht to monitor the power from shore?
Hi @sveines
I have installed the ET112 by the shore power connector, and I do see the current as a load on the CerboGX panel and in VRM, so the answer to your question is yes, it is possible. But I'm not able to assign the metered value as Shore Power, only Gen or Grid meter, and the AC input says N/A, so I assume that is why I am not able to configure monitor/alarm, either in the CerboGX or VRM.
To get AC input or shore power in the CerboGX panel and VRM I have been told that I need either a Victron Charger or Charger/Inverter by now.

Hi @vga
You can change 'Grid' to 'Shore power' within the GX. Go.. Device LIst > Settngs > System setup > AC Input.
Re alarms. VRM has a *lot* to choose from, and it'll email you. Depends what you want there, but with a Victron Multi or Quattro the relay options are wide (say if you want to run a siren). :)
Hi @JohnC and thanks for the reply. I have already tried AC Input 1 and AC input 2. Changing to Shore Power, and enabling the alarm with no success. The documentation of the Cerbo GX refers those inputs to wireless sensors only, not the ET112, so that might be why.
But I do see the ET112 under Settings->Energy Meters as 102023T, but only able to choose Generator, PV inverter or Grid.
Yes, I saw lots of options on alarms in VRM, but only under/over votage om the ET112, so I'll try that :)

Hi again,
Have now tried almost any combination there is with the ET112, and I'm not able to make it display as a AC Input, only as load or as an PV inverter (input/output). Also tried to set alarm on low voltage, but that didn't trigger when disconnecting shore power either.
So I'm a bit stuck

I have post a similar problem and a solution i think, hear:
https://community.victronenergy.com/questions/110186/vrm-alarm-rule-stop-working-for-et112.html
So, I too was testing the ET112 as an option for monitoring shore power connections without having a Victron inverter installed. I couldn't get any VRM alarms working, tried a bunch of configurations and alarm combinations.... So, I wrote something in Node-Red to do it for me. I am using SimplePush (a really nice, simple, push notification tool for node-red), instead of using email or texting for the alarms. I am using the Victron System Node and pulling the data from the Venus system (Cerbo). I am monitoring "Grid Number Of Phases" and I wrote a simple function to check the status. If it returns a "1" I send a "ShorePower is Connected" message, if it returns "null" I send a zero and a message "ShowerPower is NOT connected". Happy to share if anyone wants it, always open to feedback on a better way to accomplish the task as well.
so been stuck on this one and was looking into a energy meter as well. Anyone ever figure a a way out I dont want to learn node red right this minute. The only way I can figure is to use a 120vac to 4vdc plug adapter to trigger a digital input on the cerbo and set an alarm rule or just use a relay but having a hard time finding a relay that looks good and then with the plug I dont really want to add an outlet, proper fusing and what not for a plug. Being able to see energy usage would be nice as well
