I’m currently in the process of renovating my newly purchased home and am looking for the perfect smart thermostats to integrate into my existing setup. While I’ve done a lot of research, I’m still unsure whether to go with Zigbee or Homematic IP thermostats. Let me share my situation and criteria to get your valuable insights!
My Infrastructure:
- Running Home Assistant on a Raspberry Pi 4 with SSD
- Conbee 2 for Zigbee integration
- Over 20 Zigbee bulbs and LED panels
- AVM Fritz WIFI Mesh for reliable connectivity
- 12 Shelly 2.5 devices and 8 Shelly 1 devices
- Residential house with two floors, basement, and attic
Selection Criteria:
- Reliability: The thermostats need to be dependable, especially given the size of my home.
- Coexistence with Wifi/Zigbee: Minimal interference with my existing network is crucial.
- No Cloud Dependency: I prefer local control without relying on external cloud services.
- Manual Operation: A physical rotary wheel for adjustments is a must.
- Long Battery Life: Given the number of radiators, battery longevity is key.
- Aesthetic Appeal: The thermostats should complement my home’s decor.
- Affordability: Ideally, under €50 per unit.
Why I’m Considering Zigbee or Homematic IP:
- Zigbee seems promising due to its compatibility with my existing setup, but I’m concerned about potential interference with my Wifi mesh.
- Homematic IP offers a robust ecosystem, but I’m hesitant about the cost and the need for a virtual CCU in Home Assistant.
Questions:- Has anyone successfully integrated multiple Zigbee thermostats without performance issues?
- How does Homematic IP compare in terms of reliability and ease of setup?
- Are there any hidden costs or setup challenges with either protocol?
I’m really looking forward to hearing your experiences and recommendations! Let’s make my home’s heating system as smart and efficient as possible.
