It looks like you _may_ have based your code off the snippet I shared here: [Basic Python websockets example to retrieve current Tempest data](https://community.tempest.earth/t/basic-python-websockets-example-to-retrieve-current-tempest-data/9310/). If that is the case, the code I shared was not designed to receive multiple messages from the Websocket, and the same is true in the code you shared. Once you have sent the listen command, `ws.recv()` is only called once, and therefore you will only receive a single message.

If you want to remain connected and listen to new messages continuously, you need to wrap `ws.recv()` inside a `while` loop. Something like this will work (don’t forget to enter values for the `personal_token` and `tempest_ID`):

```auto
from websocket import create_connection

personal_token = ' '
tempest_ID = ' '

print('Opening Websocket connection...')
ws = create_connection('wss://ws.weatherflow.com/swd/data?api_key=' + personal_token)
result = ws.recv()
print("Received '%s'" % result)
print('')

print('Listening to Tempest endpoint...')
ws.send('{"type":"listen_start",' + ' "device_id":' + tempest_ID + ', "id":"Tempest"}')
result = ws.recv()
print("Received '%s'" % result)
print('')

print('Receiving Tempest data...')
while True:
    result = ws.recv()
    print("Received '%s'" % result)
    print('')

```
