# 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).

## [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.
