[homewizard] DateTime format issue with OH3.1.0

[jbuekens]

Homewizard P1 binding on OH3.1.0 windows 10 server with Zulu 11. The binding goes online, reads out the consumption numbers from the Homewizard P1 device once but then generates the following error in the openhab.log:

2021-10-03 18:10:47.117 [WARN ] [mmon.WrappedScheduledExecutorService] - Scheduled runnable ended with an exception:

The thing stays online, but P1 polling does not happen anymore.

Here is an output of the API link on the homewizard:
{"smr_version":50,"meter_model":"Fluvius 253769484_A","wifi_ssid":"telenet-7822442","wifi_strength":56,"total_power_import_t1_kwh":2425.626,"total_power_import_t2_kwh":3829.128,"total_power_export_t1_kwh":2361.773,"total_power_export_t2_kwh":883.506,"active_power_w":1448,"active_power_l1_w":1478,"active_power_l2_w":0,"active_power_l3_w":-30,"total_gas_m3":null,"gas_timestamp":null}

As you can see the gas_timestamp and total_gas_m3 show null as I do not have a gas meter. Maybe this is causing the issue?

I would think so too!
Perhaps @Daniel-42 can have a look at it?

[Daniel-42]

Yeah I will pick it up, thanks for reporting it.

[jbuekens]

Thanks for looking into this. Let me know if you need any additional info or testing.

[Daniel-42]

It's an easy fix and with the file you provided above I can test it.

Updating my dev environment to the latest version and getting Eclipse to work again to test the fix however... ah well, it will be fine.

Hi Daniel,

I tested the fix #11666 and it works like a charm! Thanks for the fast turnaround.
