Show HN: Easily connect your Arduino to your favorite internet apps (thingio.dev)

3 points by zciwor 2y ago ↗ HN

I'm building IFTT but for IoT devices. No monthly cost, just a one time deployment fee for the life of the device.

A simple MQTT interface to do all sorts of things such as: - Open a lock from a Stripe payment event - Upload images from your ESP32CAM to Google Drive - Trigger a custom email based on a high sensor reading - Log sensor readings to a Google Sheets document

Some other integrations that I have in progress: - Manage your Spotify listening session with your device (play / pause / next / volume) - Slack integration to trigger a message to your device when a new message comes in - Google Calendar integration to trigger message when you have a meeting coming up

Does anyone have any other cool integration ideas they've been meaning to implement for their WiFi projects?

So just to clarify, you've added an integration layer on top of MQTT so that MCUs can publish to a topic (for external actions) and subscribe to a topic (for MCU-driven actions)?

1. Do you have an "unexpected exit" strategy that would allow users to use their own broker, and self-host your integration layer?

2. How does the firmware/infra currently handle failed connections to MQTT? Are you using LWT?

3. Are you using retained messages and/or QoS to ensure subscribers understand the correct "state of the world" after a reconnection?

4. Does the MCU firmware support queueing messages on its own for delivery after a disconnection is resolved?
