Not to be pedantic, but you mean TP-Link (Kasa) smart lights right? I have these but haven’t bothered to block any sort of telemetry with my adguard home server. I see several domains queried that match .tplink.com but I wouldn’t want to reduce functionality as you mentioned

Ah, I wasn’t sure if they had a built-in dark mode like on apple handhelds (it works poorly on my iPad fwiw). Yeah I prefer dark mode all the time so I don’t have it alternate on a schedule. It does seem to work if I manually toggle dark mode, but maybe the issue lies with the browser recognizing when an automatic switch is made

I just use the Dark Reader extension

Remember when paranoid Android released this feature in their custom ROM 12 years ago? Pepperidge farms remembers 👴🏽
