Handling of unnamed/unused zones

[rct]

Through Home Assistant I'm getting an error:

IndexError: list index out of range on mydata.relays[self.data["relay"] - 1]

Looking at the open issues on the Home Assistant repo, I found this issue that I think may be the cause home-assistant/core#37769

I have an empty zone (2nd physical zone) that was skipped/reserved during installation which might be the cause of that error. Unfortunately, I think the referenced issue's problem description isn't very clear.

While I think the error is occurring with the home assistant integration, I'm wondering whether there is an issue with this module - should unused/unnamed zones be passed to home assistant, or should they be filtered out here?

I'm running Home Assistant 0.117, which is using hydrawiser 0.2.

Using hydrawiser 0.2 from HA 0.117 If I do

from hydrawiser.core import Hydrawiser
hw = Hydrawiser('XXXX-XXXX')
hw.relays

I don't see anything for relay 2, my unused zone. It skips from relay 1 to relay 3.

[
  {'relay_id': 2202xxx, 'time': 1576800000, 'type': 110, 'run': 0, 'relay': 1, 'name': 'Grass', 'period': 259200, 'timestr': '', 'stop': 1},
  {'relay_id': 2202xxx, 'time': 1576800000, 'type': 110, 'run': 0, 'relay': 3, 'name': 'West beds', 'period': 259200, 'timestr': '', 'stop': 1}, 
  {'relay_id': 2202xxx, 'time': 1576800000, 'type': 110, 'run': 0, 'relay': 4, 'name': 'East beds', 'period': 259200, 'timestr': '', 'stop': 1}
]

Also hw.relays = 3,
