Hello iotuser,
just to understand it right. You have a Wifi network active and a router that is providing an IP address to netPI over Wifi. Is that correct? In this case netPI operates as a "Wifi Client"
Now you have two networks in netPI active. eth0 and wlan0. In both configuration settings you will have next to the ip address, also a subnet mask and also a gateway active, right?
Now if the node-red container wants to "send something" it has two interfaces eth0 and wlan0 where he is able to send it, but now he does not know which interface shall be used for sending out data. Linux in this case does it in a very practical way: it uses the first interface that has a gateway address and sends data across this one found first. In your case it will be eth0.
So in order to get data be sent across wlan0, you have to delete the gateway address of interface eth0. Then linux will use the gateway of wlan0 address instead and will send your data over your Wifi router
