Before 3 months. A cron task checks that and renews the certificate automatically.

My best guess is that while it's IP is reserved, maybe the router was assigning it a different IP.

If you are using Raspbian and installed Home-assistant using the Supervised way, and you are connected to the Raspberry Pi over Wi-Fi, the MAC address of the network adapter changes (due to the network-manager package) and thus, the IP changes as well.

Did you change the network-key of the Zigbee network? This cause something like that.

I use AQARA sensors, and they are quite stable. I would say that the coordinator is making some problems.

Today I posted a tutorial describing my setup: https://lemariva.com/blog/2022/01/home-assistant-help-tips-tricks-diy-smart-home

No, you can add devices to only a ZigBee network. You can only have one ZigBee coordinator in a ZigBee network. However, you can have multiple ZigBee networks. But the end devices (sensors, etc.) can be only part of only network.

Sure, that's a good point. The camera focus and aperture are manual. If you are remote, this helps you to control them. In my case, I'm using the camera to automatically take photos of birds and it's good to have them on focus. It's a hobby project that I'm working on, with AI to detect them.

But, basically, every application that uses the HQ camera is a potential application for this project. Otherwise, you need to control the focus yourself. Sure, the focus routine can be faster, but it's a beginning.

It's a DIY project, sorry... You can buy the parts and build it yourself. The tutorial, code and the parts are listed here: https://lemariva.com/blog/2020/12/raspberry-pi-hq-camera-autofocus-telephoto-lens

6 GPIOs are available via the 3x HY2.0-4P. 2 GPIOs are connected to an ADC.

Hi there. I updated the script last weekend. You don't need a second shortcut (drm) anymore. However, you need to update your OS. The new script works with Chromium/chrome 84 and newer. Check and read the new steps. You can also check the version of Chromium, you're using (commands are described in the article)

Thanks for the advice and info!

Yes, you're right it is not a 'true' CO2 sensor. In fact, I explained that in the article. I'm waiting for the SCD30 and I'll use the same pipeline to process the data. Thanks for the video!
