Back in August I wrote about connecting my ISP (Altibox) fiber straight into the Mikrotik CCR1009. I’ve since decided not to include the CCR in my network stack, but instead use my EdgeRouter 4 as, well — the edge router, and VyOS to route the local networks.

So I moved the SFP module and fiber from the CCR — to the EdgeRouter 4 👇

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 👇
