This thermostat integration aims to greatly simplify your heating management automations. Since all typical heating events (nobody home?, activity detected in a room?, window open?, power load shedding?), are natively managed by the thermostat, you don’t need to deal with complicated scripts and automations to manage your thermostats. ;-).

This custom component for Home Assistant is an upgrade and a complete rewrite of the "Awesome thermostat" component (see Github) with added features.

What's new?

What's New?

• Release 7.2:

• Native support for devices controlled via a select (or input_select) or climate entity for VTherm of type over_switch. This update makes the creation of virtual switches obsolete for integrating Nodon, Heaty, eCosy, etc. More information here.

• Documentation links: Version 7.2 introduces experimental links to the documentation from the configuration pages. The link is accessible via the icon . This feature is currently tested on some configuration pages.

🍻 Thanks for the beers buymecoffee 🍻

A big thank you to all my beer sponsors for their donations and encouragements. It means a lot to me and motivates me to keep going! If this integration has saved you money, buy me a beer in return; I would greatly appreciate it!

Glossary

VTherm: Versatile Thermostat as referred to in this document

TRV: Thermostatic Radiator Valve equipped with a valve. The valve opens or closes to allow hot water to pass.

AC: Air Conditioning. An AC device cools instead of heats. Temperatures are reversed: Eco is warmer than Comfort, which is warmer than Boost. The algorithms take this information into account.

EMA: Exponential Moving Average. Used to smooth sensor temperature measurements. It represents a moving average of the room's temperature and is used to calculate the slope of the temperature curve, which would be too unstable on the raw data.

slope: The slope of the temperature curve, measured in ° (C or K)/h. It is positive when the temperature increases and negative when it decreases. This slope is calculated based on the EMA.

PAC: Heat pump

HA: Home Assistant

underlying: the device controlled by VTherm
