In node red the grid meter frequency isn’t updating.
I only get the latest frequency after deploy or restart flows.
Can this be fixed?
Just installed V3.70~20
After restarting flows , I do see the grid frequency is only ones updated exactly after 1 second.
After that the frequency stays the same, hope this helps debugging!

Is the reason of the grid frequency issue localized?
In the new remote console gui you can see grid frequency updated every second.
But this value isn’t updated in node red or in the widgets.
Is the reason why the grid frequency (EM540) isn’t updating in node-red localized?
Is this problem (grid meter frequency isn’t updating) reproducible?
Is this issue in the list of bugs, or already investigated and corrected in next firmware update?
In the new UI I can see the frequency and it is updated every second.
But in node red it isn’t updated and in the VRM widgets grid frequency resolution is very bad.
I use a EM540 hoping to see grid frequency.
Installed an EM540 because the Multiplus II AC /F IN parameter didn’t do anything.
Hi Ron,
its been noted, we’ll look into fixing this. Do you know the status of this in Venus OS v3.64 ? Also not working?
Hi Matthijs,
Thanks!
it also doesn’t work in 3.64.

Hi everyone, I have the same EM540 configuration, and it’s not working for me either. It’s not working with either 3.64 or 3.70-24. It was working a few weeks ago.
Would like to try if charging and discharging based on grid frequency is possible.
And would it be possible to change the power factor, make charging/discharging more capacitive or inductive?
Maybe in the future this could also be a market,….
latest release 3.70~26 made it worse.
The frequency now also doesn’t update after a flow restart. in 3.70~25 I often did see one update after “"restart flows”.
So something changed.
I am able to reproduce this. To be continued via Grid meter isn't updating · Issue #267 · victronenergy/node-red-contrib-victron · GitHub .
Ok thanks!
Should I keep “enable installation sharing“ open or can I close it?
You can safely close it.
Ok closed it.
If you want to test just mail me.
Fixed per v3.70~27 - thank you for reporting @ron_h .
and would be great if you can install that update and confirm.
Yes, works!
How about Multiplus II input frequency phase 1 (Hz) node, think it has the same issue.
And in VRM advance widget, could the grid frequency become a better resolution?
