May 15, 20197 yr Hi guys This is lets say a group for all the Victron owners to share information around the different topics available, and which they using and how... aka as where I try and figure out which I want to get to... At times I've noticed there are veery similar looking messages/multiple views and mutual assistance might be of benefit... we might even get Plonker to assist As a start: looking for, PV incoming from MPPT#1 ? => PV incoming from MPPT #2? => Grid incoming > /Ac/Grid/L1/Power The above is a Wattage value, is there a on / off topic ? another way might be to look at L1 Voltage => /Ac/L1/Votage, if > 0 then we have grid ? Found Grid L1 - Power, Grid L1 - Voltage and Grid L1 - Current => /Ac/L1/Power, /Ac/L1/Voltage and /Ac/L1/Current Battery SoC => /Dc/battery/Soc ... there is also => /Soc Output from Inverter to Essential line, I see => /Ac/Out/L1/P would this be the total output, the output back onto the input towards the Carlo Gavazzi or the output to the essential, Vout1 I like Charge State ... => /State indicating if we charging or discharging batteries I like PV Voltage => /Pv/V and PV Current => /PV/I , going to assume thats the combined from all Arrays... MPPT's aka a current and Voltage yield, looking for a Wattage value something like => /Pv/P, have found => /Yield/Power ? Lets the games begin.

Then you are looking for: N/d0ff500097c0/solarcharger/258/Yield/Power where 258 is your device instance. 55 minutes ago, georgelza said: Grid incoming > /Ac/Grid/L1/Power Try to use System values. There is a component called systemcalc that already does the hard work of finding out what the service name is of the vebus service, what the totals are for PV, and so on. So for grid power you'd look at: N/d0ff500097c0/system/0/Ac/Grid/L1/Power N/d0ff500097c0/system/0/Ac/Grid/L2/Power N/d0ff500097c0/system/0/Ac/Grid/L3/Power 1 hour ago, georgelza said: on / off topic N/d0ff500097c0/system/0/Ac/ActiveIn/Source 1 = grid, 2 = genset, 3 = shore power, 240 (0xF0) = disconnected 1 hour ago, georgelza said: Battery SoC => /Dc/battery/Soc ... there is also => /Soc Again, use the system value, because systemcalc already does work to decide what battery monitor to use. N/d0ff500097c0/system/0/Dc/Battery/Soc 1 hour ago, georgelza said: Output from Inverter to Essential line, I see => /Ac/Out/L1/P would this be the total output, the output back onto the input towards the Carlo Gavazzi or the output to the essential, Vout1 N/d0ff500097c0/system/0/Ac/ConsumptionOnOutput/L1/Power N/d0ff500097c0/system/0/Ac/ConsumptionOnOutput/L2/Power N/d0ff500097c0/system/0/Ac/ConsumptionOnOutput/L3/Power Download the Modbus document from the Victron website. It explains most of the paths without the N/vrm-id/service/deviceinstance prefix. Also look at the dbus wiki page. That should give you a start.
May 15, 20197 yr Author Thanks, so basically always try and use ../system/... values. will have a look at that document. was following the spreadsheet. was wondering where in those topic def's the deviceid goes. G
May 15, 20197 yr Author ... decoding what I gave... and what I'm seeing... Battery SoC => /Dc/battery/Soc ... there is also => /Soc Again, use the system value, because systemcalc already does work to decide what battery monitor to use. N/d0ff500097c0/system/0/Dc/Battery/Soc same for: Grid incoming > /Ac/Grid/L1/Power Try to use System values. There is a component called systemcalc that already does the hard work of finding out what the service name is of the vebus service, what the totals are for PV, and so on. So for grid power you'd look at: N/d0ff500097c0/system/0/Ac/Grid/L1/Power so my take away is always try and use values coming from N/d0ff500097c0/system/ as far as possible will do some subscriptions and work with data I get, thanks G
May 16, 20197 yr Author 23 hours ago, plonkster said: N/d0ff500097c0/system/0/Ac/ConsumptionOnOutput/L1/Power N/d0ff500097c0/system/0/Ac/ConsumptionOnOutput/L2/Power N/d0ff500097c0/system/0/Ac/ConsumptionOnOutput/L3/Power @Plonkster ConsumptionOnOutput, is that the ACOut1, which in my case would be going to my Essential bar. Is there a measurement that says how much the Inverter is pushing out on ACIn? aka Non Essential towards the Carlo Gavazzi. Under what topic can I find the CG, I know the DeviceId, thinking the values it's saying thats coming in would align with the values "N/d0ff500097c0/system/0/Ac/Grid/L1/Power " or is that basically where "N/d0ff500097c0/system/0/Ac/Grid/L1/Power" values originate from? G
May 16, 20197 yr 1 hour ago, georgelza said: ConsumptionOnOutput, is that the ACOut1, which in my case would be going to my Essential bar. If you have ACOut2 in use... then it would be the combined amount of the two. At least I think so... I never use AcOut2 🙂 1 hour ago, georgelza said: how much the Inverter is pushing out on ACIn? /Ac/ConsumptionOnInput/L1/Power shows power on the input side. If it is negative... then that is how much it is pushing out. But this measures (actually calculates) it for the whole installation, so if there is a current sensor/Energy meter installed, it will add that in, so if you are limiting grid feed-in to zero, then it will always hover around zero during normal self-consumption operation. So this is likely not what you want. In this case you have to consult the vebus values directly.
May 16, 20197 yr Author So this "ConsumptionOnOutput, is that the ACOut1, which in my case would be going to my Essential bar" then implies (my understanding, as a blend of all sources, this is whatever is coming from PV, from batteries and grid to serve whats being asked for. /Ac/ConsumptionOnInput/L1/Power => hmmm ok so I'm understanding this as input side, side defined as the CG. it's either positive i'm getting power, or drops down to 0 when I'm self consuming from batteries and PV (as the setup is don't feed back to grid. G

May 16, 20197 yr Hi George Have you tried logging all MQTT traffic over a few hours and then analysing the results? I setup a Home Assistant automation to Publish "R/system-ID/system/0/Serial" every minute - so that the CCGX keeps on publishing all MQTT info. I then used the following to log all messages. mosquitto_sub -h localhost -t "N/#" -v > mqtt_log.txt Edited May 16, 20197 yr by NigelL
May 16, 20197 yr Author I configured last night after allot of coffee and reading. Moving various topics from VenusGX into OpenEnergyMonitor => MQTT:Broker, via a Node-Red sub=>VenusGX and Pub=>OEM. I then also have additional rules/alerts now running on this data, that then for now just emails me... will be changed Telegram as soon as I've figured that out, which will be real time notifications then to me and wife. I'm using OEM to consolidate the Power/Energy usage and graphs and pushing management of the sonoff switches onto the HA platform, itself getting data from OEM where needed. G
June 16, 20197 yr Well, for what it's worth, attached is what I could scrape from my new MultiPlus 2 in a +-24 hour period. My VRM portal ID cleverly obfuscated with a bunch of x's Looks like "system/0/Ac/ActiveIn/Source" is what I'm after. For now. multiplus2_mqtt_topics.txt
September 21, 20205 yr Hi all, did you come to a conclusion ? I am as well looking for a "produced energy to grid" value from my Converters as it is shown on the VRM site, but I cannot find it as a MQTT topic. Any idea if this is possible meanwhile ? BR Gawan
