IndexError: list index out of range

[Sn00x]

Thanks @siku2 for your effort for the dingz integration in Home Assistant - I think you make it easier for many people to configure these smart switches.

I use several switches in blind or mixed mode (light/blinds). After v0.1.5 caused problems with the indication of the entities, they get listed with v0.1.6, but the following errors still occur in the logfile:

The error counter increases steadily and relatively quickly.

A second error that is logged, which is also apparent, but occurs less frequently, but probably has the same cause:

It would be great if you could look over here again. Thanks!

Please add the contents of the following endpoints:

• http://<HOST>/api/v1/dimmer_config
• http://<HOST>/api/v1/state

where <HOST> can be the IP of your Dingz device.

The first endpoint is used by the integration to detect the configured dimmers and the latter is used to update their states. In your case, it seems like the first endpoint reports an amount of dimmers that isn't matched by the state updates -- hence, the index out of range error.

Ah, I see. The problem is that the integration doesn't take into account that all configured dimmers are reported, even if they're not used. This is a bug in the integration that is somewhat difficult to fix, but there's a simple workaround for now:

Just go to the dimmer config page (http://<HOST>/index.html#/dimmers) and switch all unused dimmers to the type "Not connected". That way the integration will no longer try to use them.

[Sn00x]

Unfortunately, the mentioned dimmer config page does not offer the possibility to set the type to "Not connected", as the outputs configured as blinds are not displayed at all.

That is, only the 4 lamps configuration page allows to set the respective type of the 4 outputs. With the 2 lamps 1 blinds configuration only the outputs 1 and 2 are listed, with the 2 blinds configuration none at all (empty configuration page).

[Zealand67]

I have around the same error logs as Sn00x. My condiguration is blinds on output 3 and 4, output 1 and 2 are configured as I use the for testing to call a shelly api and second for Sonos.

I also encountered that the sensors (temp, lux, motion) are not being updated and show the same value since 12 hours.

You should open a separate issue for that, I don't think it's entirely related to this one.

[siku2]

Closing this as there is a new version of the integration that might address this.
