No webhooks set up by HA?

[keirlawson]

I've followed the instructions to set up the Wican Pro with HomeAssistant, however no sensor are appearing in HA. From what I can see the integration has failed to set up the webhook on the Wican device, however I can't see any errors relating to this in the HA logs. Any advice for further troubleshooting?

hello @keirlawson @meatpiHQ @jay-oswald
I can reliably reproduce this issue and if needed, I can provide some logs - if you tell me what logs should be provided, because I also wasn't able to find any errors.

In my case, the issue seem to be caused by a fact, that I am accessing my Home Assistant instance through reverse proxy with valid https certificate. When I try to add WiCAN device (Pro variant, fw4.50) no entities get created in HA and I can see that webhook is not created, as on the screenshot above.

I am able to successfully add WiCAN using v0.3.0 of this integration which does not use webhooks.

The workaround which worked for me was to access my home assistant using internal IP address, through regular unsecure http. That way, I was able to successfully set up WiCAN with latest version of the integration.

I have some additional complaints about the UX - there doesn't seem to be any verification if the communication with device is being established when performing the pairing, so I can add the device using any IP and it will seemingly work.

The same MISSING_VALUE error is displayed when adding a true WiCAN device using valid IP address, which succeeds in the end and entities get created (as long as I am accessing my HA instance through http of course). So I don't know what this error actually means.

Hope my findings will be useful to make the integration more bulletproof.

fwiw I am also accessing my Home Assistant instance through a reverse proxy with valid https certificate. Will give the workaround a try.
