Are you running Home Assistant as a docker container?

[Theetjuh]

Yeah am running it on k3s

[RobertD502]

This is more than likely due to the TZ environment variable not being set for the container and similar to issue #2. The tzlocal library needs a timezone to convert into a name, but since there isn't one, the timezoneID key in the header is empty resulting in the error that you're seeing.

[Theetjuh]

I have manually exported that setting, within the running container, but that didn’t fix it either.

[RobertD502]

Can you enter into the container and execute cat /etc/timezone.

[Theetjuh]

No such file or directory

[RobertD502]

Sorry, that's about as much as I can help since I don't use Kubernetes myself. The core issue is that a timezone doesn't exist within the container that the tzlocal library can convert to a local name.

[Theetjuh]

Setting the ENV worked, but still no /etc/timezone btw, so that isn’t part of the official docker image.

Thanks for the help, weird it didn’t work with the manual setting though.

[RobertD502]

I'm surprised that /etc/timezone doesn't exist given that Home Assistant has a Linux base so it should.

Glad the environment variable solved it!

[Theetjuh]

Yeah really nice, a big improvement over the other integration, thanks for all the work!

One thing that is shown as unavailable is the battery status on the Fresh Element Mini Pro, known issue?

[RobertD502]

Check out the documentation all is explained there 😬.

[Theetjuh]

Oops, rtfm ;)

[RobertD502]

Although I wouldn't use batteries in the mini pro. They never fixed the issue of the batteries potentially causing the feeder to lock up which results in no scheduled feedings dispensing. Problem is you never know when it may happen.

[Theetjuh]

Aahh never knew that was an issue, from what I saw in the app, the schedule is maintained.

[RobertD502]

Right, until it isn't. Installing batteries doesn't cause it to immediately lock up, but it does eventually sometime down the road.

Although this review mentions that scheduled feedings require WiFi, it is wrong since the feedings are in fact stored on the feeder. However, the unit locks up and you won't know until it is showing as offline:

[Theetjuh]

Well, will remove the batteries with the next cleanup session then, thanks for letting me know!
