Changelog

The browser flasher now understands firmware channels. Until now, flashing over USB always wrote the latest stable build — fine for a brand-new gateway, but wrong for one enrolled in the Beta program, and the only way to recover a stuck beta gateway was over the air.

New — channel-aware USB re-flash

• Flash via USB on a gateway's card jumps straight to the flasher with that gateway selected. You can also pick any of your gateways under "Re-flashing an existing gateway?" on the Add gateway page.
• The right build, automatically. A gateway on the Beta channel gets the latest beta firmware; everything else gets stable. New gateways always get stable.
• See it before you flash. A banner shows the exact version and channel that will be written — no surprises.
• Settings survive. Re-flashing preserves the gateway's Wi-Fi and MQTT provisioning, so there's nothing to re-register or reconfigure.

Partner Portal

• The commissioning wizard's Flash step gains the same Firmware target picker, so installers can re-flash a customer's existing gateway — following that gateway's channel and the customer's beta access — without re-registering it.

Details: Flash an ESP32 from your browser and firmware channels.

Reporting a bug used to be a bit of a one-way street. You'd send it, we'd fix it, and the only sign was a banner you might notice on your next visit — days later, long after you'd stopped caring.

Resolved reports now reach you

• A notification the moment it's fixed. When a report you filed is marked Resolved, you get a toast straight away if you have the app open — and a push notification on your phone if you use the mobile app with notifications turned on.
• The banner still backs it up. If you weren't around, the notice in the banner at the top of the app is unchanged, and still waits two weeks for you.
• Closed reports stay quiet. A report marked Invalid only updates the banner. We'd rather not interrupt you to tell you we couldn't reproduce something.

Reopened reports won't contradict themselves

Occasionally a fix doesn't hold and we reopen a report. Previously that could have followed the resolution notice with a second, conflicting one. Reopened reports now go quietly back to In review — the notice you already read just expires on its own.

Nothing changes about how you file a report: the report option in the topbar menu, same as before. The Help Center article covers the full status list and the plan-extension reward for reproducible bugs.

A batch of dashboard-builder improvements: faster ways to get widgets on the canvas, a new widget for reading devices on demand, and fixes for the rough edges you told us about.

New — quick-add widgets straight from your tags

• The Add Widget drawer has a new From device tags tab: every device and its tags in one searchable list. One click adds the tag to the dashboard as a ready-configured digital readout — name and unit filled in, no setup. The drawer stays open so you can add several in a row.

New — On-demand Read widget

• Shows a tag's value with a Read now button that asks the gateway to read the physical device immediately — no waiting for the next poll. Perfect for read-on-demand tags that aren't polled automatically.
• On-demand readings are streamed live but not stored in telemetry history, so your charts and storage stay clean. Reads are rate-limited to one per device every few seconds.

Improved

• No more demo data on new widgets. Freshly added widgets used to show a fake demo signal until configured; they now show a clear Not configured prompt with a one-click path to the settings panel. (The explicit Mock / Debug Signal source still works when you want it.)
• Widget titles and units fill themselves in. Picking a device tag on the Data tab now auto-fills the widget's title, label, and unit from the tag — your own custom text is never overwritten.

Fixed

• The widget picker sometimes opened empty on first click (most noticeable on new accounts with no devices) — it now always shows the catalog immediately.
• Navigating away from a dashboard with an invalid, unsaved configuration used to silently do nothing for 10 seconds. You now get a clear dialog listing what's wrong, with Stay & fix or Discard changes & leave.

Partners now have their own in-context help, right inside partner.synacl.com — so installers and resellers can find commissioning and troubleshooting guidance without digging through docs meant for account owners.

New — Partner Help Center

• Help built for partners. A separate library of articles covers the partner workflow — getting started, branding, commissioning gateways and devices, working with customers, and diagnostics — written for the partner role rather than the account owner.
• In-context and searchable. Partners open Help from inside the portal, search across the partner articles, and read them in the same light/dark theme as the rest of the workspace.

Notes

• Partner and account-owner help are kept separate: partners see only partner articles, and the main Help Center in your app is unchanged.

Installers and resellers who look after your Synacl fleet now get their own portal at partner.synacl.com — so the people who commission and support your hardware can do it without touching your account.

New — Partner Portal

• A dedicated partner workspace. Partners sign in to their own portal — branded with their company name, logo and colors — and see only the customers who have been assigned to them.
• Fleet overview at a glance. Partners see device and gateway health across the customers they support: online counts, recent events, and per-customer drill-downs.
• Guided commissioning. A step-by-step wizard walks a partner through flashing a gateway in the browser, registering it to your account, and adding the connected devices — then verifies everything comes online.
• Access you control. A partner only ever sees a customer's fleet while an access grant is active. Assigning a partner creates the grant automatically; removing them revokes it instantly. Every action a partner takes is audit-logged.

Notes

• Partner access is read-plus-commissioning only: partners can never delete devices, send control commands, or see billing.

Devices can now send telemetry to Synacl over plain HTTPS, as an alternative to connecting over MQTT. Perfect for anything that already speaks HTTP — a script, a cloud function, or a device stuck behind a firewall that only allows outbound web traffic.

New — Webhook data ingest

• A first-class protocol in Add Device. Pick Webhook (HTTP push) when adding a device — the secret is minted and ingest enabled in one step, and the endpoint + ready-to-paste curl appear on the device page immediately. No gateway, no broker credentials.
• Push data with a simple HTTPS request. Each device gets its own POST /ingest/webhook/<deviceId> endpoint. Send a JSON body of tag/value pairs and you're done — the reading shows up live on your dashboards.
• Per-device secret. Generate or rotate a webhook secret right from the device's detail page. Authenticate with either a bearer token or an HMAC-SHA256 signature of the request body — whichever you prefer.
• Flexible payloads. Send a flat { "temperature": 22.5 } and let the server timestamp it, or a native shape with your own timestamp and a quality flag.
• Same pipeline as MQTT. Data that arrives over the webhook flows through the identical path — live dashboards, stored history, threshold alerts, actions, macros and egress all work exactly as before.

One small guard that comes with this: a device's protocol can no longer be switched to or from Webhook or mqtt-direct after creation (their credentials are provisioned at create time) — create a new device instead.

When a push goes wrong, you'll see it

Previously a rejected webhook told only the device that sent it. Failed pushes now raise a warning on the Events page:

• Ingest Auth Failed — wrong or missing secret (usually a rotation the device never got).
• Ingest Bad Payload — the body didn't match an accepted shape.
• Ingest Unknown Tag — the push was accepted, but a key matched none of the device's tags. This one is easy to miss: a typo is still a 202, and the reading is filed under a name no dashboard is bound to. The response now names the unrecognised keys, too.

Each is recorded at most once a minute per device, so a device retrying in a loop won't bury your event log.

Fixed

• The Events page could show a live event with no device, detail or timestamp, and colour an offline device blue. It now shows the device name rather than its raw id, and the device filter works.
• A malformed JSON body sent to the ingest endpoint returned 500; it now correctly returns 400.

Webhook ingest is a paid-plan feature, enabled per account. Full setup steps, payload shapes and curl examples are in the Help Center.

Dashboards can now show a full process mimic — a SCADA-style schematic where your equipment, pipes and instruments come alive with real-time data.

New — Schematic widget

• Mimic canvas. Add the new Schematic (P&ID mimic) widget, then drop pumps, valves, tanks, motors, gauges, readouts and status lights onto a free-form canvas.
• Animated pipes. Connect symbols by dragging from one connection point to another. Pipes animate flow — speeding up as a value rises, or switching on/off — so you can see your process move.
• Bind anything to anything. Each symbol binds to its own device and tag (across different devices on one screen). Gauges sweep, tanks fill, pumps show running/stopped — all from live telemetry.
• Full editor. A drag-and-drop editor with a symbol palette, move/resize/rotate, layer order, grid snapping, pan/zoom and per-symbol data binding. It saves with your dashboard automatically.

Reuses the analog/SCADA widget library, so every gauge, tank and indicator you already know is available as a placeable symbol.

The Schematic widget and the analog/SCADA widget library are a premium feature — available on plans that include premium widgets. Dashboards you've already built keep working regardless.

Dashboards get a big new set of realistic, industrial-style widgets — gauges, switches, fans, tanks, meters and more — so your dashboards can look and feel like a real control panel. All of them bind to your device tags the same way as the existing widgets, in light and dark mode.

Added — analog & SCADA display widgets

• Needle gauge — a classic dial with a sweeping needle and coloured red/amber/green zones.
• Level meter / thermometer — a vertical bar (or thermometer) with a coloured scale and tick marks.
• Fan / motor — a fan that spins faster with the reading (RPM), or simply runs/stops.
• Equipment (SCADA) — a pump, valve, motor or compressor symbol driven by device state, with running animation and a fault flash.
• Nixie tube & seven-segment — retro glowing numeric displays.
• Direction dial — a compass for wind direction or heading.
• Battery — a charge-level indicator with an optional charging animation.
• LED bargraph — a segmented VU-style bar coloured by zone.
• Flow / pipe — a pipe segment with animated flow.
• Stack light — an andon tower lamp lit by device state.
• Status matrix — a grid of state cells for watching many tags at once.
• Motorized valve — shows a valve's % open position.

Added — realistic control widgets

• Rocker switch — an industrial bat-handle / rocker toggle (writes a Modbus coil/register or fires an action).
• Illuminated button — a lit momentary, latching, or emergency-stop push-button.
• Rotary knob — turn to set a value; writes the register when you release.
• Selector switch — a multi-position rotary selector (e.g. Off / Manual / Auto), each position writing its own value.
• Fan speed — an Off / Low / Med / High fan control with a live fan.

Add any of them from the + Add widget picker while editing a dashboard. See the read-only widget catalog and interactive widgets for details.

Refer a friend and your reward is more flexible. Previously, referring someone who subscribed only ever extended your plan by a fixed number of days. Now your referrer reward can also be a discount code for money off your own next plan.

Changed — referral rewards

• Discount rewards for referrers. When you refer someone who subscribes to a paid plan, your reward can now be a percentage or fixed-amount discount code (in addition to the existing "extra plan days" option).
• Rewards Earned list. Any discount codes you earn now show up under Settings → Referrals → Rewards Earned, each with a copy button and a "used" badge once redeemed. You're also emailed the code when you earn it.
• Extra-plan-days rewards are unchanged — they still apply to your plan automatically with nothing to do.

This release makes it easier to get real-world values out of Modbus and other raw sensors — especially when your device's datasheet gives a scale factor to divide by.

Added

• Divide as well as multiply when scaling a tag. Device tags now have a Multiply / Divide switch. If your Modbus (or other) datasheet lists a scale factor to divide by — for example, "the register stores the value ×10" — just choose Divide and type 10 exactly as the datasheet lists it. No more converting it to 0.1 in your head. A live example under the inputs always shows how your numbers are applied (e.g. raw ÷ 10 + 0).

Improved

• Change a tag's scaling without deleting and re-adding it. Open a device's Edit form and use Edit scaling on any saved tag to adjust its factor, direction, or offset in place — the same way you can already edit alert thresholds. For gateway-connected devices the new scaling is sent to the gateway automatically.
• Existing tags are unchanged: anything set up before this release keeps working exactly as it did, in Multiply mode.

This release focuses on fixing the things you told us about — data accuracy, device management, and general polish.

Fixed

• Sensor readings now show the correct values. Readings from polled sensors could appear mis-scaled on dashboards and history charts. Scaling is now applied correctly everywhere.
• RS-485 parity setting is back. The parity field had disappeared from the device form; it's restored.
• Gateway USB console reconnects cleanly. Returning to the provisioning page no longer fails with "port already open" — reconnecting just works.
• Deleting devices and gateways now cleans up everything. Removing a device also removes its parameters, rules, history, and dashboard references. Deleting a gateway that still has devices attached now warns you first.
• Dashboards no longer silently miss parameters. A naming mismatch could cause some parameters to never appear as dashboard data sources; they now show up reliably.
• Storage usage is measured accurately. Fixed an accounting issue in storage-quota tracking.

Improved

• Telemetry history is now kept for 365 days (up from the previous retention window).
• Dark mode everywhere. Sign-in and help pages now follow your operating system's dark-mode setting.
• Security hardening across the platform, plus better internal error monitoring so we can catch issues before you notice them.
