Hy! I am new to Node-red and java script, I need some help. I am using a WIFI node to know the WIFI strength of all the available networks. Some times I get one to two objects (networks), some times I get 10-15 (objects) based on network available. I only wants to read the signal\_level value of SSID of "TCF" (as i am connected to TCF wifi). How can I achieve this task? Is is possible to filter only TCF and ignore rest of SSID. Plus sometimes i have multiple objects with same TCF SSID name

In a change node you can set msg.payload, to jsonata(J:) `$$.payload[ssid = "TCF"]` . That should return all array objects where ssid equal "TCF".

Or  
`$$.payload[ssid = "TCF"].signal_level` would return the signal level e.g -58

You can do similar with filter() or find() in javascript.
