Asgard: The Ultimate ESPHome Interface for Mitsubishi Ecodan / Zubadan (air to water source heatpumps).
Take full control of your Heat Pump. Designed by the creator of the esphome-ecodan-hp project, Asgard bridges the gap between basic monitoring and true smart energy management.
While developing advanced auto-adaptive algorithms (free and opensource), I realized software wasn't enough. Asgard provides the hardware inputs and outputs needed to optimize your heating and integrate seamlessly with Home Assistant. Asgard connects to the CN105 port of the heatpump.
Asgard bundle comes with 3d printed case and a 2 meter connector cable (first 100 orders only).
Key Features:
- Transparent Proxy Mode: Connect safely in-between your existing controller (Melcloud/Procon). No loss of functionality.
- Virtual Thermostat: Use the hardware inputs (IN1/IN6) to simulate thermostat calls based on external sensors.
- Multi-Sensor Array: Interface for up to 4x DS18B20 temperature sensors. Measure flow/return temps accurately for precise energy calculations.
- Features a Stand Alone mode, where it can operate without Home Assistant
Complete Feature set:
| Feature | Description |

|
| Updates | OTA updates available when using the default recommended hardware |
| Short cycle detection & mitigation | Protects your heat pump from excessive on/off cycling. Documentation |
| Auto Adaptive Control | Automatically adjust flow temps to maintain room temp. (Self learning and fine tuning) Documentation |
| One wire | Allow 4 high resolution DS18x20 temperature sensors to be used |
| Virtual Thermostat | A software thermostat that controls IN1/IN6. This can replace CNRF, but allows 0.1c temp resolution |
* These features are not available in proxy, since we are observing only. Newer FTC7 will report the Outdoor unit thermistors in proxy mode.
