## User Guide: Integrating SolarEdge with EMHASS for Home Assistant
10+
11+
This guide explains how to integrate your SolarEdge solar PV and battery system with Home Assistant and optimize it using the EMHASS add-on. It covers both solar PV and battery integration, ensuring you can maximize self-consumption, reduce costs, and automate your energy usage.

15+
### **1. SolarEdge Integration with Home Assistant**
16+
17+
**A. Obtain SolarEdge API Key and Site ID**
18+
19+
- Log in to your SolarEdge monitoring portal.
20+
- Go to **Admin > API Access**.
21+
- Generate and save your API key and note your Site ID[2][8].
22+
23+
**B. Add SolarEdge Integration in Home Assistant**
24+
25+
- Open Home Assistant and go to **Settings > Devices & Services**.
26+
- Click **+ Add Integration** and search for "SolarEdge".
27+
- Select the SolarEdge integration and enter your Site ID and API key.
28+
- Complete the setup as prompted. Home Assistant will now fetch data from your SolarEdge system every 15 minutes due to API rate limits[2][8].
29+

32+
## **2. Solar PV Integration with EMHASS**
33+
34+
**A. Configure Solar PV Sensor in EMHASS**
35+
36+
- In the EMHASS configuration (via the add-on web interface or `config.json`), set the parameter for your PV production sensor.
37+
- Typically, this is the entity created by the SolarEdge integration, such as `sensor.solaredge_power` or similar.
38+
39+
Example configuration:
40+
```json
41+
{
42+
"sensor_power_photovoltaics": "sensor.solaredge_power"
43+
}
44+
```
45+
46+
- Also, define your main household load sensor, excluding deferrable loads:
47+
```json
48+
{
49+
"sensor_power_load_no_var_loads": "sensor.power_load_no_var_loads"
50+
}
51+
```
52+
53+
- If needed, create a template sensor in Home Assistant to calculate `sensor.power_load_no_var_loads` by subtracting the power of deferrable loads from your total load sensor[3][4].
54+
55+
**B. Launch and Test Optimization**
56+
57+
- Start the EMHASS optimization from the web UI or via the API.
58+
- Review the suggested schedules and outputs for your loads and PV usage.
59+
60+

61+
62+
## **3. Battery Integration with EMHASS**
63+
64+
**A. Ensure Battery Data is Available**
65+
66+
- The SolarEdge integration exposes battery-related sensors (e.g., battery state-of-charge, power, etc.) if your system includes a compatible SolarEdge battery[7][8].
67+
- Identify the relevant battery sensors in Home Assistant (e.g., `sensor.solaredge_battery_soc`, `sensor.solaredge_battery_power`).
68+
69+
**B. Configure Battery Parameters in EMHASS**
70+
71+
- In the EMHASS configuration, add the battery sensor entities:
72+
```json
73+
{
74+
"sensor_battery_power": "sensor.solaredge_battery_power",
75+
"sensor_battery_soc": "sensor.solaredge_battery_soc"
76+
}
77+
```
78+
- Set battery capacity and other relevant parameters according to your system specs.
79+
80+
**C. Enable Battery Optimization**
81+
82+
- EMHASS will now consider your battery’s charge/discharge capabilities in its optimization, allowing it to schedule when to store excess PV or use stored energy to minimize grid usage[1][3][4][6].
83+
84+
---
85+
86+
## **4. Automating and Monitoring**
87+
88+
- Link EMHASS’s optimized schedules to real Home Assistant automations for devices like water heaters, EV chargers, or pool pumps.
89+
- Example: Use the output from EMHASS to turn devices on/off based on the optimal schedule[1][3][4].

## **Summary Table: Key Configuration Entities**
94+
95+
| Function | Home Assistant Entity Example | EMHASS Config Parameter |
96+
|------------------|----------------------------------------|-------------------------------------|
97+
| Solar PV Power | `sensor.solaredge_power` | `sensor_power_photovoltaics` |
98+
| Main Load | `sensor.power_load_no_var_loads` | `sensor_power_load_no_var_loads` |
99+
| Battery Power | `sensor.solaredge_battery_power` | `sensor_battery_power` |
100+
| Battery SOC | `sensor.solaredge_battery_soc` | `sensor_battery_soc` |
101+

103+
104+
## **Best Practices**
105+
106+
- Always verify the correct mapping of your SolarEdge sensors in Home Assistant before configuring EMHASS.
107+
- Test the optimization results before automating device control.
108+
- Regularly update both Home Assistant and EMHASS for new features and compatibility improvements.
109+
