HiPi

Very much a WIP - initial goal is to toggle a smart outlet in my house when a Raspberry Pi powers on.

This switch turning on triggers a broadcast on Google Home that I use to know when utility power returns while running on a generator. (The rpi is plugged into an outlet that is hardwired to the utlity side of the transfer switch)

What's wrong with this / could use work:

• Doesn't renew tokens (since it only really runs once)
• Waits for the network to come up by just delaying - should actually hook to the state change
• Isn't a real Req plugin (again LMK if you wanna see this broken out and made nice)
• Should generate a real nonce (hard-coded for now)
• Pretty much all of it, this represents a couple days effort to solve a specific problem
  • There aren't tests, or documentation, etc

What it does / works

• Implements the mandatory parts of Tuya's request signing and request tokens to get some results
• Runs on my Pi Zero 2 W

What it needs to run for you

• If using on a Pi, you'll need to get the Nerves networking configured
• For Tuya, you need a dev account and a "project" that maps to your Tuya account
  • That is, you'll need to be able to do control from the Tuya cloud console
  • You'll need to supply environment variables (see config.exs for details)
    • TUYA_CLOUD_SECRET and TUYA_CLOUD_CLIENT_ID, you get those from Tuya Cloud
    • TUYA_CLOUD_BASE_URL unless you're OK with US West coast datacenter
