Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

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

100% Efficient Gas Boiler with Real-Time Data
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.

ESPHome
I use ESPHome to enhance existing appliances (add smart functionality to an existing aircon for example) so generally the ESP board ends up within the appliance itself with nothing visible on the outside.
For things that need to be stand-alone I'd first check if there's an existing off-the-shelf option first which generally would be more cost-effective to buy and look better than anything I could make myself.
For temp sensors specifically I generally just go with whatever off-the-shelf stuff is supported by this firmware: https://github.com/pvvx/ATC_MiThermometer

Hoe warm is het bij jullie binnen in huis?
Home Assistant, with a bunch of Xiaomi BLE LYWSD03MMC sensors, running custom firmware: https://github.com/pvvx/ATC_MiThermometer

Which bluetooth adapter has been working well for you?
I have a handful of Xiaomi LYWSD03MMC thermometers running pvxx's firmware, and a SCD4x CO2 Sensor.
-
Xiaomi temp/humidity sensor
Personally, I flashed them with this firmware so I could customize the broadcast interval and use them with Home Assistant without needing a proprietary hub.
-
Hey, does anyone have a recommendation for a temperature sensor that works well with smartlife and homebridge? For a small price on aliexpress, thank you
If BLE is an option for you, consider a Xiaomi Mijia Hygrometer flashed (wirelessly via Chrome) with this firmware: https://github.com/pvvx/ATC_MiThermometer
-
Suggested HomeKit temp sensors?
Xaomi Mija Hygrometers, wirelessly flashed with this firmware, and Home Assistant to expose them in HomeKit. Local LCD display, roughly 2yr battery life, and available from $3-5.
- Is there a battery powered low power consumption device (BLE?) that has 1 gpio pin to monitor switch state (open/closed)?

Ask HN: What's on Your Home Server?
I've been using a Raspberry Pi as a home server, and it's been holding up amazingly well, given everything I've thrown at it:
- The excellent Home Assistant, for unifying across Homekit and Google Home and tracking historical temperatures and a couple of automations. The RPi has Bluetooth built in, so I can capture the data from a few Bluetooth thermometer/hygrometers running custom firmware (https://github.com/pvvx/ATC_MiThermometer) without a 802.15.4 bridge or similar.
- An AirPlay to Google Cast bridge, mainly for listening to Overcast or the occasional YouTube video on Google speakers
- A SMB server, for file storage and potential Time Machine backups (but I don't currently have enough storage, and locally attached SSDs are just hard to beat in terms of performance)
- A DLNA server, for watching photos and videos on my TV
- Tailscale, for the occasional use of my home connection as a VPN when traveling (really glad to be having symmetric fiber for this!)
- Caddy, as a frontend for everything web facing, to benefit from its excellent Let's Encrypt integration for automatic certificate requests and renewals
Most of this is running in Docker containers and configured via Ansible, so that if the micrSD card burns out, I can just flash a new one with an empty image and recover from there.
