[aWATTar] Update prices more than once a day

[thomasleber]

Following up todays havoc on the EEX, we should consider updating the price more than once a day.

The EEX had a hick-up today, spiking the price in Germany and Austria up to 4€ per kwh.

The plugin would only update the price once at 1500 (afaik from code). The prices seemed normal at 1500 CEST. But at 1508 it seems an update occurred, showing new data.

The plugin would not update the prices, leading the schedules to not be aligned with the updated data.

Expected Behavior

New marked prices will be used when an update occurs.

Current Behavior

Scheduler will update once a day at 1500, ignoring all the following updates.

Possible Solution

Schedule more often an update eg. at 1500, 1800, 2300

@thomasleber Can you check with the latest code (i.e. 4.3.0-SNAPSHOT)? I believe this is also fixed by #17032.

Hi @J-N-K

Unfortunately i don't think so. The line that controls the refresh is afaik this one: https://github.com/openhab/openhab-addons/blob/main/bundles/org.openhab.binding.awattar/src/main/java/org/openhab/binding/awattar/internal/handler/AwattarBridgeHandler.java#L188

The API is only checked once, if the data in the time range is older than 15h.

[thomasleber]

localPrices.last().timerange().start() < Instant.now().toEpochMilli() + 9 * 3600 * 1000; will return true when the the current time plus 9h is larger than last entry of todays prieces.

I have tried to fix that here: https://github.com/openhab/openhab-addons/pull/17068
