# Changelog

All notable changes to econet-exporter are documented here. The format is
based on [Keep a Changelog](https://keepachangelog.com/en/1.1.0/), and this
project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html).

## [Unreleased]

### Added

* Optional Grafana dashboard shipped as a ConfigMap in the Helm chart. Enable
  with `hull.config.settings.grafanaDashboard.enabled=true`; the ConfigMap is
  labeled `grafana_dashboard: "1"` for the Grafana sidecar to auto-import. The
  dashboard uses the default Prometheus datasource (no hard-coded UID) and has a
  multi-select `Device` filter driven by `econet_friendly_name`. Covers connect/
  heating/mode/setpoint/hot-water/alerts, setpoint range, hot-water availability,
  energy + cost + water usage, a heating-state timeline, WiFi signal, and a
  device-info table. Sidecar label/value and Grafana folder are configurable.

## [v0.3.0] - 2026-07-05

### Changed

* Replaced the third-party `kevinburke/rheemcloud-go` dependency and its MQTT
  coupling with an in-repo `econetclient` REST poller that talks directly to
  the Rheem/EcoNet cloud REST API. Device state (including `@RUNNING`, `@MODE`,
  and `@STATUS`) is sourced from the REST `getUserDataForApp` payload, so no
  MQTT connection is required.

### Removed

* `rheemcloud` package and its `go.mod`/`go.sum` entries.

## [v0.2.0] - 2026-07-05

### Added

* `econetTLSInsecure` config option (env `ECONET_TLS_INSECURE`) to skip TLS
  certificate verification when
  connecting to the Rheem/EcoNet cloud API. The upstream host (cloudblade)
  serves an old/untrusted certificate chain; this is a stopgap and should be
  removed once the upstream certificate is fixed. See AGENTS.md.
* `TODO.md` tracking outstanding work (CA cert bundle, mutating proto RPCs,
  additional tracing spans).

## [v0.1.2] - 2026-07-04

### Added

* CA certificate bundle baked into the container image so the exporter can
  establish TLS connections to the EcoNet API.

### Changed

* Bumped Helm chart versions.

## [v0.1.1] - 2026-07-04

### Fixed

* Corrected the Helm chart `appVersion`.

## [v0.1.0] - 2026-07-04

Initial release of the EcoNet exporter for Rheem / Rheemcloud water heaters,
built on the `go-app` framework.

### Added

* `EconetService` owning a single shared `*rheemcloud.Client` across the gRPC,
  MCP, and metrics sub-servers (fail-fast on missing credentials).
* gRPC API (`ListDevices`, `GetDevice`) with proto definitions and
  grpc-gateway REST bindings.
* MCP server at `/api/mcp` exposing a `list_water_heaters` tool.
* OpenTelemetry observable gauges for device state (temperature, mode, energy
  and water usage, cost) with a background usage poller, exported to
  Prometheus. Units are encoded in metric names (`_fahrenheit`, `_kwh`,
  `_gallons`, `_dollars`).
* `costPerKWH` config (US dollars per kWh) feeding `econet_energy_cost_dollars`.
* Helm chart for Kubernetes deployment.
