Node-red on Cerbo: can read but not write value

Hi there,

I've installed "venus-swu-einstein-20210416100626-v2.70~5-large-18.swu" image firmware to be able to use node-red.

All seems to be good. I can read different values with nodes like "ESS control" but impossible to change values !

Any ideas .....

Hi, I know several people are using Venus OS large to change values, and all works for them.


So to get people here to help you, please provide some more details. Ie. what value are you trying to change? And how?


all the best, Matthijs

The ESS node is for reading:

The ESS Control node is for writing:

You should be able to change the following parameters:

Is the issue maybe that you want to change something else (other than these 3 parameters) or that it doesn't work?
