Particle handles cellular connectivity. Blynk handles the application layer. Here's how the two platforms work together and what you can build.
Particle's hardware ships with a SIM card, connects to LTE Cat M1 out of the box, and handles carrier switching across 150 countries through EtherSIM. Their newer Muon adds WiFi and LoRaWAN, with satellite available on the MUON635 variant. For getting a device connected to a cellular network, Particle has the problem well covered.
What Particle doesn't include is the application layer your customers actually interact with. There's no drag-and-drop dashboard builder, no branded mobile app you can publish to the App Store, no multi-tenant user management for deploying to end customers across multiple organizations. Particle's platform is built for device management and connectivity, not for the end-user experience.
That's where Blynk comes in. Particle handles the device side, Blynk handles everything after the data arrives: web dashboards, native iOS and Android apps, automations, alerts, fleet management, and OTA updates.
The two platforms connect through webhooks. Your Particle device publishes data to Particle Cloud using `Particle.publish()`. Particle Cloud fires a webhook to Blynk's HTTPS API. Blynk receives the data, updates your datastreams, and displays it on dashboards and mobile apps.
Going the other direction, Blynk can trigger Particle Cloud Functions to control the device, toggle relays, change settings, or push configuration updates.
Device → Particle.publish() → Particle Cloud → Webhook → Blynk HTTPS API → Dashboard/App
Blynk App → Blynk Webhook → Particle Cloud API → Particle.function() → Device
The device never talks to Blynk directly. Particle Cloud handles the cellular connection, and webhooks bridge the two platforms over HTTPS. This keeps the device firmware simple and cellular data usage minimal.
Once the integration is in place, you have the full Blynk platform available:
Monitoring: Live gauges, charts, and maps on both web and mobile. Historical data storage (up to 12 months on the Production tier). Track temperature, humidity, GPS location, battery level, signal strength, or any sensor data your device can read.
Control: Toggle relays, change settings, trigger actions from the Blynk app or web console. Commands flow through Particle Cloud Functions so they reach the device reliably over cellular.
Automations: Set up rules based on device state, schedules, or sensor thresholds. Get push notifications or emails when something needs attention.
Fleet management: Deploy multiple devices from the same template. Each gets its own dashboard, but you can create unified views across your entire fleet. Multi-tenant organization structure lets you give different customers access to only their devices.
Branded mobile apps: At the Enterprise tier, publish a custom-branded app to the App Store and Google Play using Blynk's low-code app builder. No mobile development team needed.
Any device that supports `Particle.publish()` works with this integration:
Blynk has a pre-configured Particle Blueprint in the console. Install it, and you get a ready-made template, pre-built dashboard, and step-by-step activation guide.
For a custom integration, our documentation covers the full setup:
Both guides include complete firmware examples, webhook configuration, and troubleshooting steps.
The webhook approach scales without architecture changes. Each device gets its own Blynk auth token, but they share the same Particle webhook definition and template. Adding a device means creating a new device from the same template and flashing the firmware with the new token.
For production fleets, Blynk's Production tier starts at $199/month for 100 devices with 12-month data retention and technical support. Particle's pricing scales separately based on data operations.
For ESP32 users comparing approaches: The key difference is connectivity. ESP32 handles WiFi natively and connects to Blynk directly using Blynk.Edgent. Particle's value is cellular connectivity without the complexity of managing modems, SIMs, and carrier relationships yourself. If your deployment needs cellular, Particle + Blynk is a strong combination. If WiFi is sufficient, ESP32 with Blynk.Edgent is simpler and lower cost.
