I’ve been pondering the oddity of certain lightbulb switching related to Sense detection, specifically the Philips WIZ above my head.
It uses rapid human-initiated switching to change modes.
Switch ON/OFF rapidly enough and the bulb will change from a cool color temperature to warm and back.
The bulb is also directly controllable through WiFi but I’m trying to be as non-smart as possible at home so the networked aspects are never exploited (dimming!). Admittedly, I don’t even bother with the mode switching (warm forever).
Meanwhile a few bulbs have been migrated to those with integrated motion detection. I’ve had to experiment with different bulbs because they all have different hardware-locked ON cycles and limited motion sensitivity. Generally too sensitive. All less ideal than a separate motion sensor but much easier to retrofit in a closet with no light switch.
Anyway, in general now the bulb ONs & OFFs present different signatures to Sense. No more (or less) detectable I suppose on the 1/2s timescale or by more sophisticated means but in the case of the rapid ON/OFF switching to change modes there is, as it were, a little Morse evolving in my wires.
“Sense, can you hear me?”
Neighbors?: Have they seen Panic Room?
The motion detection bulb’s long ON cycles preclude easy communication with Sense by doing a Motion Detection Dance BUT surely Sense’s 20-dimensional brain will eventually work out this bulb has a 1 minute on cycle and that bulb has a 10 minute cycle?
And so enough of the idle rhetoric and to my core pondering …
Are not devices in general becoming sophisticated enough, incorporating cheap nano-scale electronic control circuitry, that two options present themselves:
A standard evolves by which a device innately broadcasts, down it’s power feed, it’s power state.
I’m DeviceUPScodeXgenY going ON.
I’m going OFF. “I’m OFF” reminds me of Bruno Munari
I’m using X watts (this is tricky I believe).
I’m changing power state, “Hey Sense how much did I just ask for?” That could be a challenge.
Sense develops a cute inline plug. Specifically NOT like Kasa/Wemo in that it does not communicate via WiFi and not even via PowerLine Ethernet but that it exploits Sense’s higher frequency current/phase/voltage-variation over-sampling (as it were) ability and COMMUNICATES via BEHAVIOR. Inject some COMMS.
My strong preference would be #1. This is more like RT-PMP.
And note, this may sound like I’m simply suggesting that RT-PMP extends to the “local” (household) level for ALL devices vs just the power-hungry ones that can afford to have control circuitry and be controlled by an external agent. It’s not that simple: RT-PMP can actually live separately from device signature identification and power tracking.
“It’s an EV, it wants a lot of power, not now”
In theory it doesn’t even need it. In practice, I believe, RT-PMP and disaggregation would both benefit from low-level device communications, regardless of the device.
#2, Sense Babies, violates the simplicity rule. Perhaps.
There should be a few more notes here but I will just point out that HSPLC (High Speed Powerline Communications) are more complicated in the U.S. due to the power distribution method vs. Europe. That’s an indication of the non-trivial nature of these musings.

Just another blackout-gossip enabler?
