+# Home Assistant -> InfluxDB -> Grafana setup and debugging notes
+## Architecture
+
+This setup has **three layers**:
+
+1. **Home Assistant** generates state changes and sensor values.
+2. **InfluxDB 3 Core** stores that time-series data.
+3. **Grafana** reads from InfluxDB and visualizes it.
+
+### Network layout
+
+- **Home Assistant** runs outside the Docker Compose network.
+- **InfluxDB** and **Grafana** run together in the same Docker Compose stack.
+- Therefore:
+  - **Home Assistant -> InfluxDB** must use the **Proxmox container IP** and exposed port.
+  - **Grafana -> InfluxDB** should use the **Docker service name**.
+
+## Actual endpoints
+
+### Home Assistant -> InfluxDB
+Home Assistant should connect to InfluxDB using:
+
+- Protocol: `http`
+- Host / URL: `192.168.194.120`
+- Port: `8181`
+- SSL verification: off
+
+Reason: Home Assistant is outside the Docker network, so it cannot resolve `influxdb3`.
+
+### Grafana -> InfluxDB
+Grafana should connect to InfluxDB using:
+
+- URL: `http://influxdb3:8181`
+
+Reason: Grafana and InfluxDB are on the same Docker Compose network, so Docker DNS resolves `influxdb3`.
+
+## Docker Compose setup
+
+The relevant Compose structure is:
+
+```yaml
+services:
+  influxdb3:
+    image: influxdb:3-core
+    ports:
+      - "8181:8181"
+
+  grafana:
+    image: grafana/grafana:latest
+    depends_on:
+      - influxdb3
+    ports:
+      - "3000:3000"
+```
+
+This means:
+
+- InfluxDB is reachable from outside Docker at `http://<proxmox-container-ip>:8181`
+- InfluxDB is reachable from Grafana internally at `http://influxdb3:8181`
+
+## Home Assistant InfluxDB configuration
+
+### Important migration detail
+
+Home Assistant is removing YAML-based InfluxDB **connection settings**.
+
+So these connection keys should **not** stay in YAML:
+
+- `api_version`
+- `host`
+- `port`
+- `ssl`
+- `verify_ssl`
+- `ssl_ca_cert`
+- `username`
+- `password`
+- `database`
+- `token`
+- `organization`
+- `bucket`
+- `path`
+
+Those should be configured through **Devices & Services** in the Home Assistant UI.
+
+### What can still stay in YAML
+
+Behavior/settings like these can still stay in YAML:
+
+- `measurement_attr`
+- `default_measurement`
+- `override_measurement`
+- `include`
+- `exclude`
+- `tags`
+- `tags_attributes`
+
+## Final Home Assistant behavior setting
+
+To get **one table per entity/sensor**, the key YAML setting is:
+
+```yaml
+influxdb:
+  measurement_attr: entity_id
+```
+
+Reason:
+
+- Default behavior grouped data into tables like `W`, `Wh`, `V`, `%`
+- That made many sensors appear "missing", because they were grouped by unit
+- `measurement_attr: entity_id` changes that back to one measurement/table per entity, which is easier to use in Grafana
+
+## InfluxDB concepts in this setup
+
+### Databases
+We used databases such as:
+
+- `home`
+- `homeassistant`
+- `ha_fresh`
+
+These are databases, not tables.
+
+### Tables / measurements
+Inside a database, tables are created automatically when data is written.
+
+Examples after using `measurement_attr: entity_id`:
+
+- `sensor.solarnet_power_photovoltaics`
+- `sensor.solarnet_power_grid_export`
+- `sensor.solarnet_power_load_consumed`
+
+Examples from the old grouped schema:
+
+- `W`
+- `Wh`
+- `V`
+- `A`
+
+## Tokens and authentication
+
+### What is used where
+
+- **Home Assistant** uses an InfluxDB token to write data
+- **Grafana** uses an InfluxDB token to query data
+- **Admin token** is used for CLI/database management
+
+### Important note
+Tokens and secrets that were exposed should be rotated.
+
+## How we debugged the setup
+
+## 1. Verified InfluxDB is running
+
+We checked Docker:
+
+```bash
+docker ps
+docker logs --since 0.5m influxdb3
+```
+
+This confirmed:
+- Grafana container is running
+- InfluxDB container is running
+- InfluxDB is actively flushing writes
+
+## 2. Verified databases exist
+
+```bash
+docker exec -it influxdb3 influxdb3 show databases --token "$INFLUX_ADMIN_TOKEN"
+```
+
+This showed databases like:
+
+- `_internal`
+- `home`
+- `homeassistant`
+- later `ha_fresh`
+
+## 3. Verified Home Assistant can reach InfluxDB over the network
+
+From Home Assistant shell:
+
+```bash
+curl http://192.168.194.120:8181/health
+```
+
+Response:
+
+```text
+{"error": "the request was not authenticated"}
+```
+
+This was **good** because it proved:
+- DNS/IP was correct
+- network path worked
+- InfluxDB was reachable
+- only authentication remained
+
+## 4. Reconfigured Home Assistant in the UI
+
+Home Assistant InfluxDB integration was configured in **Devices & Services** using:
+
+- HTTP
+- host/IP of Proxmox container
+- port `8181`
+- no SSL verification
+- organization `dummy`
+- bucket/database `ha_fresh` or similar
+- token
+
+## 5. Enabled debug logs in Home Assistant
+
+We confirmed HA was writing by seeing log lines like:
+
+```text
+Wrote 8 events.
+Wrote 10 events.
+```
+
+That proved:
+
+- Home Assistant -> InfluxDB write path works
+
+## 6. Verified writes actually landed in InfluxDB
+
+We queried InfluxDB directly:
+
+```bash
+docker exec -it influxdb3 influxdb3 query   --database ha_fresh   --token "$INFLUX_ADMIN_TOKEN"   'SELECT * FROM "W" ORDER BY time DESC LIMIT 20'
+```
+
+This showed fresh rows from Home Assistant sensors, including:
+
+- `pv_power`
+- `solarnet_power_photovoltaics`
+- `solarnet_power_load_consumed`
+- `solarnet_power_grid_export`
+
+That proved:
+
+- Home Assistant -> InfluxDB works fully
+- the issue was not ingestion
+- the issue was schema / Grafana config
+
+## 7. Verified Grafana container can reach InfluxDB
+
+From inside the Grafana container, we tested:
+
+```bash
+curl -i http://influxdb3:8181/api/v3/query_sql   -H "Authorization: Token YOUR_GRAFANA_TOKEN"   -H "Content-Type: application/json"   --data '{"db":"home","q":"SHOW TABLES"}'
+```
+
+This working proved:
+
+- Docker networking is fine
+- `influxdb3` resolves correctly
+- Grafana-side token auth works
+- the remaining problem was purely Grafana datasource configuration
+
+## 8. Fixed Grafana datasource setup
+
+### Correct Grafana datasource basics
+
+- Query language: **SQL** or the desired mode
+- URL: `http://influxdb3:8181`
+- Database: the actual InfluxDB database in use
+- Token: Grafana token
+
+### Important TLS issue
+
+Grafana originally failed with an error like:
+
+```text
+tls: first record does not look like a TLS handshake
+```
+
+That happened because Grafana tried TLS/FlightSQL behavior against a plain HTTP endpoint.
+
+Fix:
+- use the correct datasource mode
+- use the right endpoint
+- keep the connection consistent with the actual InfluxDB setup
+
+## 9. Realized the schema had changed
+
+Old schema assumption:
+- one table per sensor
+
+New schema that appeared initially:
+- one table per **unit**, like `W`, `Wh`, `V`
+
+That is why old queries stopped working.
+
+Example old query:
+
+```sql
+SELECT mean("value")
+FROM "sensor.solarnet_power_photovoltaics"
+WHERE $timeFilter
+GROUP BY time(5m) fill(none)
+```
+
+Equivalent query in the grouped-by-unit schema:
+
+```sql
+SELECT mean("value")
+FROM "W"
+WHERE
+  "entity_id" = 'solarnet_power_photovoltaics'
+  AND $timeFilter
+GROUP BY time(5m) fill(none)
+```
+
+Then we changed HA back to per-entity measurements using:
+
+```yaml
+influxdb:
+  measurement_attr: entity_id
+```
+
+## 10. Reset the fresh database to keep it clean
+
+After confirming the new schema worked, the goal was to keep only actually-used tables in the fresh DB.
+
+General approach:
+- delete or recreate `ha_fresh`
+- reconnect HA to it
+- let HA repopulate it with only actively written entities
+
+That leaves a clean database without old junk.
+
+## Final recommended setup
+
+## Home Assistant
+- Configure InfluxDB connection in the UI
+- Keep only behavior options in YAML
+- Use:
+
+```yaml
+influxdb:
+  measurement_attr: entity_id
+```
+
+if per-entity tables are desired
+
+## InfluxDB
+- Keep one clean database for HA data
+- Use separate tokens for:
+  - admin
+  - Home Assistant
+  - Grafana
+
+## Grafana
+- Use datasource URL:
+
+```text
+http://influxdb3:8181
+```
+
+- Point it to the correct InfluxDB database
+- Use the Grafana token
+- Rebuild old queries if schema changed
+
+## Quick troubleshooting checklist for the future
+
+### If HA is not writing
+1. Check HA logs for InfluxDB errors
+2. Test connectivity from HA:
+   ```bash
+   curl http://<influx-ip>:8181/health
+   ```
+3. Verify token / database / organization / bucket in HA UI
+4. Query InfluxDB directly to see whether data is arriving
+
+### If Grafana shows nothing
+1. Verify datasource URL is `http://influxdb3:8181`
+2. Test token from inside Grafana container
+3. Confirm the right database is selected
+4. Check whether schema is per-entity or grouped-by-unit
+5. Rewrite queries accordingly
+
+### If sensors seem missing
+1. Check `SHOW TABLES`
+2. Query likely shared tables like `W`, `Wh`, `V`
+3. Check whether HA is grouping by unit instead of entity
+4. Set:
+
+```yaml
+influxdb:
+  measurement_attr: entity_id
+```
+
+if one table per sensor is preferred
