Feature Request: Changeable Refresh Time

[TheChosentwo]

Hi, I used the add-on now for some weeks and I really love it, great work!

I saw in your Code that the Sensor is refreshing every 30 Seconds, I found that is a bit often.

It would be great if everyone can change it for their own preferences.

I never tried to create an add-on but I found some tutorial where they wrote, you can add an options.json file that can handle this feature request.

If you need more Information, please write back.

Kind regards

Yes, this sounds reasonable. I put this fast update rate, because I don't want the next train to be shown "five minutes ago". (Also, KVB delays tend to magically appear out of nowhere in the last minute before departure. 😉)

Can you point me to this options.json documentation? If it is that simple, we should definitely do it. If it's more difficult, we could still add an option to the sensor configuration.

I did some searching and it appears to me, the scan interval of polling sensors is intentionally not configurable in HA anymore. See documentation. Instead, the recommended way to customise the polling interval is to write an automation for it. See here for an example:

Thank you for the fast reply!

I found the information on this website:

I will try your idea too in the next days, but it is not so easy when the add-on don't work atm.

I found the information on this website:

This is about add-ons, which is basically a software separate from home assistant, such as MQTT brokers. It doesn't seem to provide for setting scan intervals for custom components.

I will try your idea too in the next days, but it is not so easy when the add-on don't work atm.

Yes, that's a disappointing development... I'm not sure yet how to handle this.

My idea was, that you can dynamically adjust the value in the sensor.py file where you set the scan_interval.

SCAN_INTERVAL = timedelta(seconds=30)

With the help of the options file.
That you can edit this value over the ui and it will be updated becouse it is a reference from the sensor.py to the option.py file.

[..], the recommended way to customise the polling interval is to write an automation for it. See here for an example:

Amazing. Just what I wanted. I want dynamic pollings (night, rush hour, ..) which would be too much to ask - but now I can fix it myself.

Thanks for the integration. It works beautifully. :)
