We’re using Tibber as our electricity supplier — we have the Tibber Pulse reading our power usage and making it available in Home Assistant, through an integration.

But Tibber also controls our heat-pump, by interfacing a Sensibo Sky. Tibber’s smart heating control takes multiple factors into account; outside temperature, power price, thermal inertia. A clever algorithm, made by clever people — it works really well 🙂

I found an easy way to “hook into” this heat control, using a simple Home Assistant automation.

We recently got balanced ventilation installed, and I have interfaced it with Home Assistant. However — the ventilation unit have three “special modes” that can not be enabled through the Modbus interface; fireplace, kitchen, and override. These can only be set on the touch panel, mobile app, or through inputs terminals on the controller.

So I repurposed an old project and made a three-relay Wi-Fi controlled module, using MQTT to send commands and receive statuses.

Then used Home Assistant to automate it 🙂

Using a few cheap sensors, a wireless keypad, Zigbee2MQTT and Home Assistant; I was able to get a basic security alarm up and running during a free afternoon 🙂

We recently got balanced ventilation installed, and discovered that our ventilation unit has Modbus TCP/IP support. I even found a thread on the Home Assistant community talking about interfacing the C6 controller, which our unit has, into Home Assistant 😃

Here is my implementation 👇

We have a Raspberry Pi driven digital calendar in the kitchen. I’m currently using crontab to turn the HDMI port off at night, and when we’re at work.

But a much more flexible solution is to control it using MQTT and Home Assistant. That way it can easily be automated to turn on when we’re home, if there is movement in the kitchen, or any number of conditions.

It’s really quite easy to do, here’s how 👇
