Connecting and powering 4 different devices over single ethernet cable is a very nice use case for various sensors. Hell, even for IoT, ethernet/IP is pretty simple protocol compared to BT stack, wifi+ip, or zigbee, just plug in and power your sensor/switch/relay with 2 wires directly into local ethernet network, no bridges needed, and pretty safe too vs any radio.

  If you're dragging cables sure, but you might have a ethernet cable already in place. Currently option is to get a PoE-powered switch and split it off that way which is extra device to manage.

  I feel like SPE has a lot of potential for IoT, sensors, etc. Well, maybe some cheap PLC could compete too, but the multi-drop and PoDL capabilities are quite interesting for dispatching a few $3 sensors. I kind of want to run SPE over old coaxial cables that are quite commonly found in relatively recent houses. Add a cheap ESP with I2S, an I2S DAC and a speaker, and you get a smart multi-room speaker setup.

    If you have coax, you already have a sufficiently shielded connection so you wont need a twisted pair. You can just modulate an RF signal down the line - I think there is even a standard for it that is not DOCSIS for sending small data packets.

    The multidrop capable 10Base-T1S is much shorter range (around 30meters) than the long range point-to-point 10Base-T1L (+1000meters). 10Base-T1S also does not tolerate too long "branches" from the main trunk, so can't run it old phone wiring in a house for example.
