Since I've replaced ioBroker with Home Assistant, I also wrote an article about integrating M-Bus devices via MQTT with HASS. Another post, doing the same with wmBus can be found…
Integrating wmBus devices into iobroker
STM32 BLDC Motor Control
Introduction ST offers quite a broad BLDC controller portfolio, but the most interesting to me seems the STSPIN family of controllers. They include mostly anything except the MOSFETs to drive…
Merging the Contents of Two InfluxDBs
Eveer had the problem that data runs into two different influx databases and you want to merge the data into a single one? You wonder, why this can happen? Then…
Headless Rescue System over SSH
Again, I stumbled over some problem... I need to draw some backup disk image of a headless bare metal server, to run a risky update of atlassian tools. And yes,…
STM32 UART Continuous Receive with Interrupt
My last post is quite some time ago, due to vacations and high workload. But now I encountered some problem within an embedded project, I want to share the solution…
How to build a Smart Home
Since everbody complains about smart homes are vendor lock in, too expensive, giving you data for free to some suspecting cloud provider,... I need to preset my smart home solution…
OrangePi 4G-IoT Complete Pack
Since Andorid 8.1 is quite slow on the OrangePi 4G-IoT, I decided to give Andorid 6 a try. OrangePi.org also provides mega.nz-links for these packages, which is quite inconvenient... Here…
How to Build A Private Storage Cluster (with Ceph)
Finally, I did not succeed in getting Ceph running on a 32 bit ARM. There have been to many issues in the code (especially incompatible datatypes) and issues with GCC…
Compile Ceph (master) on ARM (32-Bit)
I gave up on getting Ceph run on ARM 32 bit. It was a huge effort to fix the types, that diverge when switching from 64 to 32 bit. The…
Compiling Software on RAM-limited Multi-Core Systems
Since I often compile stuff on embedded ARM targets that are well equipped with processing power (Exinos Octa-Core), but are neglected regarding RAM (2G), I often facing the trade-off between…
