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.
Sorry i made i mistake in the debug node. Now everything is working fine as you have mentioned in earlier. Thanks for your help.
