Trigger API according to the input

General
1

I'm building a weather dashboard and it has two options to get input. City/ Country name or Lattitude/ Longitude.
I want to update my dashboard every 30 seconds.
If City/ Country was given as input, I want to update the relevant OpenWeatherMap API every 30 seconds and get new data.
If Lattitude/ Longitude. was given as input, I want to update the relevant OpenWeatherMap API every 30 seconds and get new data.
The problem I'm facing is, that when I change the input type (ex: city/ county to lat/lon) in the middle, the program starts updating both APIs in 30-second intervals.

This is how my current flow looks

Combine the two into a trigger that sends "stop" then 50ms later sends latest msg object. follow that trigger with another trigger set to resend every x seconds, and reset if payload = "stop". then you would only require one openweather node.
e.g.

[{"id":"53d0947e.3a38e4","type":"inject","z":"bf9e1e33.030598","name":"","props":[{"p":"payload"},{"p":"topic","vt":"str"}],"repeat":"","crontab":"","once":false,"onceDelay":0.1,"topic":"","payload":"brighton","payloadType":"str","x":130,"y":1380,"wires":[["e11d68b3.2fed58"]]},{"id":"e11d68b3.2fed58","type":"function","z":"bf9e1e33.030598","name":"","func":"msg.payload = msg.payload + \"qwerty\"\nreturn msg;","outputs":1,"noerr":0,"initialize":"","finalize":"","libs":[],"x":290,"y":1380,"wires":[["b3068fb3.5d7068"]]},{"id":"b3068fb3.5d7068","type":"trigger","z":"bf9e1e33.030598","name":"","op1":"stop","op2":"","op1type":"str","op2type":"payl","duration":"50","extend":false,"overrideDelay":false,"units":"ms","reset":"","bytopic":"all","topic":"topic","outputs":1,"x":490,"y":1420,"wires":[["14095796.cf6488"]]},{"id":"dd970f6d.bd2cd8","type":"function","z":"bf9e1e33.030598","name":"","func":"msg.payload = msg.payload + \"qwerty\"\nreturn msg;","outputs":1,"noerr":0,"initialize":"","finalize":"","libs":[],"x":270,"y":1460,"wires":[["b3068fb3.5d7068"]]},{"id":"14095796.cf6488","type":"trigger","z":"bf9e1e33.030598","name":"","op1":"","op2":"0","op1type":"pay","op2type":"str","duration":"-5","extend":false,"overrideDelay":false,"units":"s","reset":"stop","bytopic":"all","topic":"topic","outputs":1,"x":710,"y":1420,"wires":[["8f20800d.7d01d8"]]},{"id":"75706316.d56be4","type":"inject","z":"bf9e1e33.030598","name":"","props":[{"p":"payload"},{"p":"topic","vt":"str"}],"repeat":"","crontab":"","once":false,"onceDelay":0.1,"topic":"","payload":"lat/log","payloadType":"str","x":100,"y":1460,"wires":[["dd970f6d.bd2cd8"]]},{"id":"8f20800d.7d01d8","type":"debug","z":"bf9e1e33.030598","name":"","active":true,"tosidebar":true,"console":false,"tostatus":false,"complete":"false","statusVal":"","statusType":"auto","x":680,"y":1480,"wires":[]}]

Does the weather really change that fast ? Are there rate limits on hitting that API ?

This does not work as intended.
As long as I keep giving one type of input (say city/ country), it works. But, when I change the input type to (lat/ lon), the OpenWeather API keeps getting the last inputs from the previous input type.

Then Use a switch and filter if has property city, and have two openweather nodes, or use a http request node and construct the http request
here is a http request example add you api key in the function node.

The free call limit is -

60 calls/minute
1,000,000 calls/month

The weather does not change that fast, but this is a requirement of the project I'm working on.
The rate limits are not mentioned. I use the current weather data free version
