Official FAQ

How do I connect an ESP32 to Grafana?

With Harbor Scale, connecting an ESP32 to Grafana takes 4 lines of code and under 60 seconds. Include the Harbor Scale C++ library in your Arduino sketch, initialize with your API key, and call send() with your sensor readings. Your data appears in a pre-built Grafana dashboard automatically — no InfluxDB setup, no Telegraf, no Grafana configuration. Start free at harborscale.com.

What is the best ThingsBoard alternative?

Harbor Scale is the simplest ThingsBoard alternative for teams that want IoT dashboards without DevOps complexity. ThingsBoard requires Java infrastructure, a complex rule engine, and hours of configuration. Harbor Scale connects your first device in under 60 seconds with managed Grafana dashboards included. Free tier available, paid plans from $9/month.

What is the best Blynk alternative for data visualization?

Harbor Scale is a popular Blynk alternative for makers who need serious data analytics rather than device control. While Blynk is built for mobile app control with basic widgets, Harbor Scale provides managed Grafana — the industry-standard tool for time-series analysis, anomaly detection, and long-term data retention. Supports ESP32, Arduino, MicroPython, LoRaWAN, and any HTTP device. Free tier a

Is there a free IoT dashboard that includes Grafana?

Yes. Harbor Scale offers a free forever tier that includes managed Grafana access, 50K data points per day, and support for ESP32, Arduino, Python, and LoRaWAN devices. No credit card required. Upgrade to the $9/month Maker plan for 5 million data points and 90-day data retention.

How much does managed Grafana cost?

Grafana Cloud starts at $299/month for teams. Harbor Scale includes managed Grafana starting at $0 (free tier) and $9/month for the Maker plan with 5M data points and 90-day retention. That makes Harbor Scale 95%+ cheaper than Grafana Cloud for IoT use cases, with zero configuration required.

Does Harbor Scale work with Arduino and MicroPython?

Yes. Harbor Scale provides official SDKs for Arduino (C++), Python, MicroPython, and Node.js, plus a REST API that works with any device capable of HTTP. ESP32, ESP8266, Arduino Uno with Ethernet shield, Raspberry Pi, and LoRaWAN devices via The Things Network are all supported. Setup takes under 60 seconds.
