standard-readme VS ikea-tradfri-coap-docs

HomeAssistant also have a workaround and as far as I can tell from using it HomeKit scenes also work with colour temp and brightness at the same time. Some users report that Ikea Home scenes work as well and giving both commands via COAP works as well - https://github.com/glenndehaan/ikea-tradfri-coap-docs

Got Ikea Tradfri E14 and E27 bulbs, non-colored, that go from very warm (orange-ish even) to very white.

The good: Entirely local. No cloud needed (and none exists). Hub does not phone home, except to query for updates, which is done without any extra metadata (this has been scrutinized[0] by multiple people). Updates have very synthetic but sensible changelogs. Hub provides an API over CoAP that has been reverse engineered[1], and is actually quite sensibly designed. Bulb-remote pairing and operation does not require hub at all, which is only used by the app for advanced features and discrete control. This means one can choose not to have a hub at all, or that should LAN be down for any reason - or for guests that don't have the app/lan access - there is a graceful degradation path from the app to the remotes.

The bad: Lowest dimmer setting could be lower, at night I feel it's still quite bright. Not blessed by HomeKit for Adaptive lighting. I wish mains-powered remotes that replace physical switches exist, instead of CR2032 thingies (I blocked the physical switches so that the bulbs are never powered off, which would kill automation when guests or old habits cut power via the switch. If I want to cut power I do it via the circuit breaker panel).

The ugly: my E14 bulbs have some coil whine when light is out. Issue is known and widely reported, not sure if it's been fixed in recent production batches.

The used-to-be-ugly: at first everything was perfectly working, then some updates broke stuff: hub loss of IP connectivity seemingly after DHCP lease expiration, some bulbs would desync/crash, requiring pairing them again, and other connectivity issues. IIRC this lasted a year and then a batch of updates were released addressing each issue in turn.

Hello everyone. I've had Trådfri at my house for a couple of years now and it works great. One thing I've tried to do ever since I got these lights is to automatically control the warmth and brightness based on time of day. To achieve this I was first using HomeAssistant, but since it didn't have any such feature built in I resorted to writing my own extension (which is quite a chore as they are a full docker image, my poor RPi2B was struggling). After having broken HomeAssistant twice for other reasons I decided to try out OpenHab because it's supposed to be better for scripting. While it was easier to get the script working the rest of the experience was a bit more cumbersome, and out of nowhere all my lamps just decided to disappear one day. So I went one step deeper, since neither HomeAssistant nor OpenHab seemed to work for me why not build it myself? So I started looking at how these integrations talked to the bulbs and wrote my scrip to interface with the bulbs over CoAP directly. I found this repository https://github.com/glenndehaan/ikea-tradfri-coap-docs which has some user-generated documentation of the interface, but I was wondering if it would be possible to get some kind of official documentation for this? Someone at IKEA surely has something written down about this, and it would greatly help all 3rd party interactions and make IKEA Trådfri stuff work better for everyone.

The Ikea hub specifically doesn't report events on motions sensors, I've tried it myself, and it's also explained here.
