SAT VS adaptive-lighting

If your boiler supports OpenTherm, check out https://github.com/Alexwijn/SAT

You can have your thermostat in home assistant and make your boiler run as efficiently as possible at the same time

SAT (Smart Autotune Thermostat) is a free integration you can add to Home Assistant, which can work with your existing thermostat but the intention is that it replaces it altogether (SAT becomes your virtual thermostat). There are many more features but it's best to head to https://github.com/Alexwijn/SAT for details.

OpenTherm is a standard communications protocol which SAT uses, however, you need this hardware - https://www.nodo-shop.nl/en/featured/211-opentherm-gateway.h...

The installation is usually very simple, you connect two cables to the boiler and its OpenTherm module in the boiler and then it uses MQTT to connect to Home Assistant via WiFi. If you are not comfortable touching the boiler, ask your plumber to help you.

By the way, that hardware is much cheaper than Hive which does not support OpenTherm at all. Google Nest does but is so extremely limited, and from my experience, it was cycling too often and did not autotune which is the main reason why you want SAT.

If you check the manufacturer of your boiler and its model, you should be able to find out if your boiler supports OpenTherm.

This is new build~ (2017) but we are not the first owners of the house and personally, I would probably not try to retrofit such system.

I use Home Assistant for doing most of what you're asking for. This integration works great for adjusting light level and temperature: https://github.com/basnijholt/adaptive-lighting.

My home has an ERV and I use a couple Shelly relays (one for power and the other to boost airflow) integrated into HA to modulate the amount of fresh air I bring in, currently based on indoor/outdoor temperature and humidity. I don't have an air quality sensor, but if I had one I could easily integrate that into my automations.

Are you using any sort of home automation system (Google, Alexa, Siri, other) or just using the Kasa app? I use Home Assistant along with the Adaptive Lighting integration with my bulbs and LED strips, which works on circadian rhythm and does exactly what you're wanting to do.

My home has never felt this "smart" before. Every time my lights turns on I find the color and brightness to be perfect.

If you're starting from scratch with a new build, I would recommend Home Assistant with the Adaptive Lighting Custom Component.

Personally, I use this Integration within my home automation hub. It took all of 5-10min to set up, didn't require any additional hardware, works with all of my existing bulbs and strips with CT and/or brightness control, updates my lights every 90s, and slowly transitions to the next setting over a 45s period. Any time I make manual adjustments to any light, it holds that setting until I turn the light off.

Probably not the solution you're looking for, but I use Adaptive Lighting with Home Assistant. Doing it at the hub level (instead of the bulb or app level) means you aren't restricted to a specific brand/protocol. As long as the light has dimming and CT controls, it just works. (I use it with several different LED strips and several different smart bulbs.)

I think the best method to do this is with this home assistant integration: https://github.com/basnijholt/adaptive-lighting

Any CCT capable light will be able to achieve this, but the level of automation will depend on the app/hub you pair them with. Inovelli, Ikea, and Philips have some good options, but will all require an appropriate Zwave/Zigbee hub. Personally, I run Home Assistant in conjunction with the Adaptive Lighting Add-On to handle the CT automations.
