Nostr Internet of Things

Ratioanale

The terms/conditions of IoT software/hardware is horrible. A user should be able to message a light or heating and ask it to turn on/off. Nostr gives the simple, permissionless development enviroment IoT needs.

All communication happens over NIP04.

Terms

• user - user operating IoT device with NOSTR key-pair and a client made specifically for IoT
• device - device to operate over Nostr with NOSTR key-pair, using a microcontroller client like nostr-arduino

Nostr IoT Clients

User

Where the user registers 'device'(s) and its keys, then updates the device(s).

Device

The device uses a client like nostr-arduino to receive commands from the user or another device. The devie can also push data such as senssor readings and updates.

User OR device registering/updating a user OR device

A merchant can publish these events:

Kind		Description	NIP
4	direct_message	Communicate between device(s) and user(s). The messages can be plain-text or JSON.	NIP04

Event: Register a device

Event Content:

{
    "id": <String, UUID generated by the user.Sequential IDs (`0`, `1`, `2`...) are discouraged>,
    "device_id": <String, UUID of the stall to which this device belong to>,
    "name": <String, device name>,
    "description": <String (optional), device description>,
    "categories":[ <String (optional), device category, such as 'boiler'>],
    "users":[ [<String (optional), user public-key>]],
    "images": <[String], array of image URLs, optional>
}

Note:

• users:
  • A list that can restrict access to public-keys, device(s) also has keys and can be a user.

Event: Update a device

Event Content:

{
    "id": <String, UUID generated by the merchant.Sequential IDs (`0`, `1`, `2`...) are discouraged>,
    "device_id": <String, UUID of the stall to which this device belong to>,
    "settings":[ [<String (optional), user public-key>]]
}

Note:

• settings:
  • Standard settings innclude:
  • eg: [["on", <bool>], ["range", <int, 0-1000>], ["timer_on", <int unix timestamp>], ["timer_off", <int unix timestamp>]]
