I know that the following value is available in MQTT ‘Ac/ConsumptionOnOutput/L1/Current’ which is the consumption current of all the devices on L1.
I can get the power value of L1 via the Node red ‘Venus System’ palette but not the current, and as the voltage varies trying to use a static conversion value leads to inaccuracies.
Can anyone suggest where I might find this value, or anyway that I can accurately calculate the current draw.
The reason that I would like to us the value directly from the Victron node red palette is that my MQTT is on a seperate device and if there are ever any issues with that device the data would not be available.
Easily done with custom input nodes, either selecting the individual device or system power out.
These are quite well documented on git and in the register list etc which is the best place to start.
There is a device that meaures the current elsewhere in the system and I need to measure the current within the node red script that I am writing (this script is running on my Victron device). I can get the amps using MQTT, but the MQTT broker runs on a seperate PC and I would prefer not to be reliant on another device.
If the node red script gets all it’s data from the Victron device, if that fails no problem as the node red script will not be running, but if a seperate PC fails and the Victron node red script is dependant on the input would cause a big problem.
Just select the drop down list, you can see what is on offer.
The same is documented in the register list.
It really is straight forward. This is from a single phase system hence null values.
I was missing something in node red and I saw that there was an upgrade to the palette available. Once I had upgraded I got more options in the drop down boxes and all is good.
