Circadian vs “dim to warm” (lemmy.world)

submitted 1 year ago by [email protected] to c/[email protected]

22 comments fedilink hide all child comments

I just read a great article about a company wanting to do Circadian lighting on the International Space Station! It was very inspiring, so now I want to look into automating that. Up until now, my priority has been smart switches (both Zigbee and Z-Wave) and voice control, but I also have an automation to dim when it’s bed time.

Can anyone compare Circadian vs “dim to warm”, by how happy you are with results, cost, complexity? I guess I’d have to get all new bulbs either way, but I’d have to rewire and reconfigure switches for smart bulbs to do Circadian and I’d have to actively automate, vs “dim to warm” would just do it

Personally, I have colour-capable bulbs in my bedroom (paired with a smart switch). Using Adaptive lighting (https://github.com/basnijholt/adaptive-lighting) was a breeze to setup and offers more capabilities than I even need.

I can vouch for Adaptive Lighting. I use it in every room and it was very easy to set up.

It can be a bit tricky when working with scenes though – that's maybe the only downside I've come across.

Is that on HACS?

Yep

Off topic, but I noticed that I had issues replying to your comment in my Lemmy app (Voyager). I’m trying to work out why.

Logging in via a web browser, I can see that the post and parent comments are tagged as English, but your comment language is Undetermined. If I tag my post as language Undermined, my reply doesn’t get sent, just shows a loading animation. If I change it to English, it posts, but I’m not sure if that will display for you. Please let me know if you see this message.

This could be preventing some people engaging with your posts. In Kbin settings, can you define the language of your posts?

[–] [email protected] 3 points 1 year ago* (last edited 1 year ago) (2 children)

This comment appears to be set as English, let me know if that changes anything. The previous comment appears to be set that way too. But I did set my profile to filter to english posts so maybe Kbin is auto-setting it now?

[–] [email protected] 2 points 1 year ago

That one is showing as Undetermined as well. I setup a Kbin account and had the same behaviour, comment was set to English in Kbin, but would appear as Undetermined on Lemmy.

The issue with replying from Lemmy seems to occur when Communities have set their Language to only English (or at least not Undetermined). For some reason the Kbin supposedly Undetermined messages are allowed to post, but if anyone on Lemmy tries to reply to it, Lemmy will try to use the same language, which will result in a silent error (but visible in Developer Tools).

Again, manually changing my reply on Lemmy to specifically use English works.

In conclusion there’s probably nothing you can do, but there is an issue for Lemmy language issue here.

Hey there, a patch for the reply issue was added to Lemmy 18.3. I’m just testing if it seems to have fixed it.

[–] [email protected] 1 points 1 year ago (1 children)

Good news, Lemmy 18.3 did fix it, no issues replying to you and I didn’t have to manually select my language, it was auto set to English! Hopefully 18.3 gets rolled out to everyone’s instances posthaste!

Sweet! Thanks for the update.

I like the circadian lighting addon in HACS. All my bulbs are white spectrum bulbs as circadian lighting is the reason I got into home automation and smart bulbs years ago. I do think I sleep much better.

[–] [email protected] 5 points 1 year ago

I like the idea of circadian lighting in theory, but in practice I really just want one specific warm light all day, then red a couple of hours before bedtime.

[–] [email protected] 3 points 1 year ago (1 children)

I have Hue lamps around the house that are daylight temperature in the day and turn warm and dim in the evening on a schedule. Is this what you mean by circadian, or is it something else?

[–] [email protected] 4 points 1 year ago* (last edited 1 year ago) (2 children)

Yes.

A smart bulb with controllable color temperature can be configured to be whiter in the day and warmer into the evening and night. The idea is to better mimic the sun to reinforce our circadian rhythm, and improve sleep. I believe Home Assistant has at least two integrations that can control lights this way.
vs recently there are new dimmable LEDs that automatically change to whiter when bright and warmer when dim, similar to the natural behavior of incandescent bulbs.

These are two different approaches that probably have very similar results (since I already have an automation to dim as it gets later)

I love the idea of these bulbs. I'm using the adaptive lighting component so my bulbs' temperature and brightness are always correlated anyway. For light fixtures with more than one bulb, a single smart dimmer could replace a whole zigbee light group.

However, are there any bulbs on the market yet with a good temperature range? So far, the only ones I've been able to find are Philips Warm Glow lamps that only go from 2200K to 2700K, which is way too warm for daytime use.

Test, please ignore.

Maybe HASS is better than this but it’s not simple to schedule Hue to have the right colours at the right time. At least, not at my latitude. I’ve got separate summer and winter schedules and that helps a lot, but especially in the summer it’s pointless using the built in sunset/sunrise events.

[–] [email protected] 1 points 1 year ago

I modified an AppDaemon script found on HACS as I found that the regular warm-when-dim was not ideal. Now, it starts to dim an hour before sunset, but starts to warm only after sunset. It feels more natural this way... This is by far the feature that I enjoy the most on my installation.
