### Hardware that works with Blynk library or HTTPs API (using Static Tokens)

{% hint style="info" %}
This is the easiest way to migrate from legacy Blynk projects. Just add `BLYNK_TEMPLATE_ID` and `BLYNK_TEMPLATE_NAME` at the top of your firmware (prior to any includes), update your auth token and that's it. Read more about [project migration](https://docs.blynk.io/en/troubleshooting/blynk-1.0-and-2.0-comparison/migrate-from-1.0-to-2.0).

{% hint style="info" %}
Traffic optimization is usually required for cellular connections. Using realtime streaming protocols like Blynk or MQTT has benefits of interactive device updates, but it also requires device to stay "always connected", which significantly increases the traffic. Blynk recommends using [HTTPS (batch) API](https://docs.blynk.io/en/blynk.cloud/device-https-api/upload-set-of-data-with-timestamps-api) for reporting telemetry and fetching `DataStream` values periodically in such scenarios. It will also help saving the battery.
