  • I operate a rooftop solar power station. While I have scripted all the individual components like battery management, Inverters and the various sinks (for where the power goes when it’s not needed immediately) using Grafana to get alerts, I use automation to activate the various scenes and settings to maximise the useful power I get from the system.














  • Bear in mind that full 4K HD with 4:4:4 sampling requires around 18Gbps of bandwidth.

    You can send HMDI signals over Cat6/Cat7 cable using the HD-BaseT protocol. Lots of companies like Extron, Kramer and Crestron make those adapters, and provided your cabling is good quality then you’ll not lose resolution. These are point to point devices.

    An alternative is AV over IP where you use a regular Cat5e/Cat6 cable run and dedicated encoders and decoders that stream the signal. Atlona and Wyrestorm make these and they’re pretty good - very low latency and a range of compression options. You can also attach a network switch and have a one-to-many setup or a matrix with multiple inputs and outputs.
