RainPoint Local integration 0.18.6 alpha

RainPoint Local integration 0.18.6 alpha

Use with gateway 0.39.19 and radio firmware 0.21.0.

HTV213FRF setup no longer requires a dedicated radio or manual tuning. On firmware 0.21.0, sensors and valves can share a radio, with up to eight HTV213 associations per radio. Existing working associations can stay in place.

In HACS, enable prerelease versions and select v0.18.6, then restart Home Assistant. Do not select a firmware-v* tag as an integration version. Update the existing gateway and radios separately; HACS installs the integration, not the gateway or radio firmware.

Agent update and short testing guide · Getting started

Shared operation has source/replay coverage; mixed-installation alpha feedback is requested. Test valves dry or visually confirm opening and closing. HTV213 battery percentage and water-volume scaling remain unqualified.

Radio firmware 0.21.0 alpha — shared radios

Radio firmware 0.21.0 alpha

Use gateway 0.39.19 and integration 0.18.6 with this release.

• Sensors and valves can share a radio; up to eight HTV213FRF associations per radio.
• HTV213 pairing uses tested default carriers. Manual tuning and a dedicated radio are no longer setup requirements; existing tuning overrides remain effective.
• Saving a valve preserves its real completion-report state and observation time.
• Response-window restoration, a larger bounded frequency cache and reconnect backpressure improve mixed-device operation.

Start with Getting started, or give an updating agent the attached TWO_ZONE_ALPHA_TESTING.md. Install the matching integration release through HACS with prereleases enabled.

rainpoint-radio-0.21.0.zip contains the production-signed application, USB support images and OTA catalog. rainpoint-source.tar.gz contains the matched gateway and integration. Check SHA256SUMS and the ZIP's internal checksums before use. Existing adopted radios should use OTA, not a full USB-layout flash.

HTV213 pairing, both outlets, automatic stop and early stop were RF-verified on a spare radio. Shared multi-device behavior has source/replay coverage; alpha feedback on mixed installations is welcome. Other two-zone models, battery percentage and water-volume scaling are not qualified. Test dry or visually confirm opening and closing.

Radio firmware 0.20.0 alpha — two-zone support

Firmware alpha for existing RainPoint Local installations

Unified radio firmware 0.20.0 adds native HA pairing and two-outlet controls
for HTV213FRF, alongside the existing moisture-sensor, single-zone and
four-zone paths. Use gateway 0.39.18 and HA integration 0.18.5.

Give your setup agent the two-zone update and testing guide.
It covers upgrading an existing installation, signed OTA, pairing, both
one-minute outlet tests, early stop and optional restart/battery recovery.

Two-zone scope

• One dedicated ESP32/CC1101 radio per HTV213FRF, with saved calibration for
  that physical radio. A firmware update does not create that calibration.
• Normal HA pairing discovers the valve, completes both-port configuration,
  waits for real confirmation and saves one device with two outlet controls.
• Bounded controls, independent outlet state, retained battery rejoin and
  observation-only missing-response/restart recovery.
• This model has been qualified on the project's dry valve; independent radio
  calibration/setup remains alpha work. Do not copy another radio's correction.
• Battery percentage, water-volume scaling and simultaneous outlet operation
  are not qualified. Turn off the stock gateway for pairing and initial tests.

Use a dry valve or visually verify opening and closing. Pairing success alone
does not prove successful watering. No two-experiment unlock or 72-hour wait is
required. Report both successes and failures through
GitHub issues.

Downloads and update order

rainpoint-radio-0.20.0.zip contains the exact signed application, receipt-matched
first-USB-flash parts and offsets, signed OTA catalog, public verification key,
compatibility metadata, checksums and instructions. For an adopted radio, use
OTA; the full USB layout is only for first flashing a new classic 4 MB ESP32.
Never flash the standalone firmware.bin at address zero.

rainpoint-source.tar.gz contains matched gateway 0.39.18 and integration 0.18.5
source. It is not an HA backup. Use the app store/HACS when the matching version
is offered, otherwise follow the agent guide's pinned source installation.
Update gateway/integration first, stage the signed catalog, then update one
idle radio at a time and verify healthy boot. Publication does not automatically
update any installation. This firmware-only tag is not an integration tag to
select in HACS; the original Alpha 1 stack and its downloads are unchanged.

Provenance

• Firmware and matched stack source: f10903302cca7b31c3213dc56d8ef222edd4207f.
• Approved production signing run: https://github.com/fholgado/rainpoint-local/actions/runs/37289662174.

• Application size: 1,117,376 bytes.
• Release-key image installed on Test Node B with healthy OTA confirmation,
  development trust removed and its saved two-outlet association/phase retained.
• Both one-minute HA outlet runs have independent RF confirmation on the unified
  development candidate; no additional RF control trial was claimed during
  production-image handback. Automated suite: 1,067 tests passed.

The release tag points to the actual approved firmware source. Newer agent
instructions are bundled and linked above. See the
roadmap
for remaining qualification.

RainPoint Local — Alpha 1

RainPoint Local — Alpha 1

The first public alpha of the complete local stack is available for builders
with HCS02x/HCS026FRF sensors, HTV145FRF single-zone valves and HTV405FRF
four-zone valves. No stock RainPoint gateway, cloud account or SDR is needed.

Component	Alpha 1 version
RainPoint Local Gateway (HA app/add-on)	0.39.0
RainPoint Local (HACS integration)	0.18.0
Unified classic ESP32/CC1101 firmware	0.19.0

This release labels the current working stack; it does not change the RF
implementation or rebuild the approved signed firmware. Existing installations
on these versions need no reflash or re-pair solely for the Alpha 1 label.

Install

Give the agent-assisted getting-started guide
to your agent. It covers the parts list, HA gateway/HACS installs, flashing,
Wi-Fi adoption and HA pairing. Use Home Assistant OS with Core 2026.7.0 or newer and the
classic 4 MB ESP32 reference hardware (not C3/S3).

In HACS, select v0.18.0-alpha.1 rather than main or the firmware-only tag.
HACS downloads only the integration. The app repository follows main, so check
that it offers gateway 0.39.0 or use the pinned source archive. OTA catalogs must
be staged locally before firmware offers appear in HA; publishing does not
automatically update nodes.

Downloads

• rainpoint-source.tar.gz: gateway and integration runtime source from this
  release. Not an HA backup; see the bundle guide.
• rainpoint-radio-0.19.0.zip: the exact previously published signed firmware
  bundle, including USB flash parts/offsets, signed OTA catalog and instructions.
• compatibility.json: separate stack and firmware source revisions, component
  versions, firmware identity and artifact checksums.
• SHA256SUMS: verify with shasum -a 256 -c SHA256SUMS (macOS) or
  sha256sum -c SHA256SUMS (Linux) after downloading all three assets above.

The original firmware signature is retained and verified; no new signing key
or same-version replacement image was created. Older plaintext/TLS-only stacks
need the coordinated upgrade procedure, not an isolated firmware update.

Help finish validation

Both valve families and sensors are included now. We welcome independent
fresh-install, pairing/deletion/re-enrollment, longer-soak, battery-change and
stock-gateway-coexistence reports. Multiple single-zone valves per radio also
need physical qualification. Those tests remain open, not prerequisites for
joining the alpha and not claims of proven reliability.

HTV405 battery is not decoded and it has no water-volume capability. Standalone
HA Container manual TLS onboarding is not yet supported; use HA OS discovery.
Household dashboards and watering automations are not installed automatically.
HA watering notifications are enabled by default; mobile forwarding is optional.

For first valve tests, run dry or visually confirm opening and closing, and
keep another way to water. See known limitations
and the live roadmap.
Report successes or problems through the alpha issue template,
including versions, models, timestamps and steps; redact credentials and personal data.

Radio firmware 0.19.0 (alpha)

Firmware-only alpha prerelease

Radio firmware 0.19.0 for the unified classic ESP32/CC1101 node, covering
HCS026 moisture sensors, HTV145 single-zone valves and HTV405 four-zone valves.

This publishes the exact existing approved, publisher-signed build already
qualified on the project's three radio nodes. No RF implementation or pairing
settings were changed to produce this release.

• TLS transport and publisher-signature verification for OTA updates.
• Unified sensor/valve pairing, telemetry, ACK handling and valve controls.
• Use with gateway 0.39.0 and HA integration 0.18.0.
• Classic 4 MB ESP32 (esp32dev) only; not ESP32-C3/S3.

Downloads

rainpoint-radio-0.19.0.zip includes matched first-USB-flash binaries and offsets,
the signed application, installable OTA catalog, build receipt, compatibility
metadata, public verification key, checksums and instructions.

Standalone firmware.bin and firmware-signature.json are also attached for
OTA tooling. Do not flash the standalone application at address zero. See
the bundle README for the complete first-flash command.

Existing nodes already on this exact image need no update. Release publication
does not automatically install or advertise firmware in your local gateway;
stage the OTA catalog to expose it in Home Assistant.
