Best way to write to multiple nodes at once?

[TheWicklowWolf]

When reading multiple values, read_values(nodes) works well. What is the equivalent for writing multiple values?
I'm using the Client from asyncua.sync

def write_values(self, nodes, values):

When I use write_values, I get: BadWriteNotSupported(2155020288)

"The server does not support writing the combination of value, status and timestamps provided."(BadWriteNotSupported)

I can write a single value using: write_attribute(ua.AttributeIds.Value, ua.DataValue(float(value))

What am I missing?

Nevermind, just used:

write_values(nodes,[ua.DataValue(float(v)) for v in values])

you need to use the correct varianttype

Got it working, thanks
