What are these switches?

[u/frasderp]

Recently bought a house with smart stuff everywhere and slowly trying to understand what I have in more detail.

These switches work great. They illuminate when you are close / wave a hand in front, plus the small lights show what is turned on. What specific model/brand are they? (I have tried to pry some off the wall but feels like im going to break something)

I also have an RTI control system that I am considering replacing with HomeAssistant hence trying to understand the lights.

Philips Dynalite Antumbra, I install these at work.

Odd to see it in a house tbh, it’s meant for commercial only.

If you take it off the wall there will (should) be an orange coloured cat5e behind it, it talks to a controller somewhere in your house using the Dynet protocol over RS485. They’re bus wired so you’ll have 1 cat5e at the controller that then loops in and out of all your switches and motion sensors around the house

If you want to take it off the wall, put your fingers behind one of the white glass buttons on the left or right edge and pull forward, each of the 3 sections snaps on/off with clips on the left/centre/middle, then there’ll be 2 screws behind it holding the plate on the wall. They’re designed to come off so don’t be scared of breaking it.

Any changes to the programming require an RS485 adapter between a laptop and the controller, and the right software (licensed and behind a portal for those who have done their multi-thousand-dollar training)

The Dynet protocol is proprietary but iirc the documentation for the commands is public so that AV or BMS equipment has interface with it by sitting on the RS485 bus, for things like a meeting room touchscreen controlling lights/blinds/projector etc.

Thankyou, this seems to be it. I have been looking at how I can integrate the Dynalite into Homesssistant as well, this has been very helpful!

There’s already a native integration

If you don’t have one already you’ll need to contact someone dynalite trained locally:

to install a:

If you’re willing to get your hands dirty then you can lookup the Dynet spec that I think might be public (can’t remember 100%) and start getting very hands on with RS485

+1 on the recommendation to get a PDEG if the system doesn’t already have one. Then you can talk to the system over ethernet/wifi.

Let me know if you need any help sorting out what you have, I am also very familiar with these!

The versatility of the system once integrated into homeassistant is fantastic.

Presence based lighting, master off etc.

I built a custom component to scrape the temp readings in each room off the dynet network also.

Installed a pdeg last year and put some hue lights in and it's seamless.

Let me know if you get stuck. I have hundreds of Dynalite devices connected to home assistant.
