I am trying to create a node red flow on Home assistant that will do the following
Check battery % of car
Check current electricity cost
Based on the above 2 turn on the car charger
Then switch off the car charger if current cost or batter % goes out of a predefined range
Somthing like the following
If battery% \< 20 and current cost \< 0.15 turn on charger, if either of those become not turn switch off charger
If battery% \>=20 & 0\<=50 and current cost \<=0.05 turn on charger, if either of those become not turn switch off charger
If current cost \<0 turn on charger, if above 0 turn off charger
I think I can get the battery % out using poll state & use switch node to define what to do when the battery % is a certain amount but I'm not sure how to combine 2 different if statements for different entities.
I also can't work out how to switch a device on/off like in home assistant, can anyone shed some light?

We can help with the Node RED specific Nodes - but you will need to seek support from HA for rest
The first thing to do, is share your Flow where we can answer Node RED specifics.
again - be VERY specific about the properties you want to query as no one here will understand HA, and is better suited being asked at the HA forums

I was reccomended to use node red on the HA subreddit and for some reason though it was a sub module of HA.
I think I'm going to leave node red for now.

Not a HA user
There is a sub category for node-red on the HA forum, where you will get more specific help about HA
Saying that have you attempted to use the state change node to monitor the battery?
