    At this weekend I finally established another network in my home — a ZigBee network. A looong time ago (in 2010 year) I touched the ZigBee networking in my university (ITMO, previously IFMO, in Saint-Petersburg) — these times it was a new technology, not used widely. And as a student I have some fun time playing with ZigBee main router, supplemental router and end-devices. You can view old photos and screenshots of old software on a my extremely old blog: http://h0rr0rr-drag0n.blogspot.com/2010/04/cc2530zdk.html (and read a blogpost, if you understand Russian).It is kindly fascinating, that now, after 15 years, I can just buy some ZigBee-powered devices from AliExpress (using Black Friday discounts) and connect them to the network inside my house right in the way I did it in the university 15 years ago!Sadly, although I bought native supported main router device, based on the EFR32MG2 with some software from Ember (EZSP v8) inside, the OpenHAB doesn't support this device natively — it supports it, but since my server is running NetBSD, I got problems with some bundled with OpenHAB things. Looks like some native libraries (rxtx-java) don't have bundled NetBSD versions. And the same library in the repository built for Java 8, not for Java 17.So, I decided to use Zigbee2MQTT, not to build the necessary Java library myself. It was kinda scary — use program, which connects my ZigBee network via ZigBee USB-dongle to the MQTT server — which is written on JavaScript . Not on the C (as I can totally understand, for a such low-level program, operating with embedded devices) or at least on the C++/Perl/Python/whatever. But, looks like it works good enough, if I don't try to pair the device in wrong mode (my window sensors has two modes to pair them with network: first "common" mode causes zigbee2mqtt to silently crash and the second "compatible" mode works without problems).And I could understand now, why people has so much problems with smart home security. Installed MQTT server mosquitto — it allows unauthenticated connections by default. Installed zigbee2mqtt — it allow connections to frontend without any password by default At least these two services don't each much memory: 1.2 Mb for Mosquitto and 75.6 Mb for ZigBee2MQTT.For now, my ZigBee sensors works pretty well and robust, like these devices from university 15 years ago #HomeAutomation #OpenHAB #ZigBee #HomeLab

    @stefano Running Leap 16 in VirtualBox 7.1 on my Debian laptop. Leap 16 has some problems.First, it only successfully boots every *other* time it powers on. The other times, after the boot loader, it shuts down automatically with no warning.Secondly, there are strange network issues though this may be a Virtual Box thing. I just tried installing Debian 13 and the network config during the installer is continuously failing at DHCP. I'm on public wifi at a hospital, but that shouldn't matter because the laptop itself and my phone connect to the wifi no problems. I suspect I have some troubleshooting to do there....but only being able to successfully power up every other time? Yeah, that is strange.

    My #HomeLab has a corrupted boot disk because of a failed rebuild of btrfs. I did the rebuild, because btrfs reported errors most likely because of power outages. I thought why not try to fix this and than it failed after days of calculating, because the USB thumb drive was ejected. Quite forcefully because of a falling broom I might add. It was a whole thing.Currently in the middle of reinstalling the boot disk. But during the wait I was thinking I probably should acquire a small #UPS for my setup. Any recommendations on what one want’s to get these days? I mainly need a small one and ideally I’d want it to communicate with the server when there is a power outage to shut it down (after an appropriate time of course).#FediHelp
