## Project ideas

- A room-temperature history dashboard

- A humidity reminder for a plant room

## What you need

- H&T Gen3, batteries or appropriate USB power, Wi-Fi and a home automation host.

- A laptop and coding agent for writing and reviewing your project

## Compatibility and cautions

- Battery-powered reporting is not a continuous high-rate data stream. Use the Gen3 instructions, not the separate Shelly BLU H&T route; security and reporting behavior depend on firmware.

- Documentation reviewed, not hands-on tested by Atoms for Agents. Generated code needs review before it controls real hardware.

## Planning notes (not a replacement for the original technical instructions)

1. **Confirm the exact model**: Match the hardware label and bundle to the linked documentation. H&T Gen3, batteries or appropriate USB power, Wi-Fi and a home automation host.

2. **Prove the documented connection**: Follow the original guide and run its smallest supported example before asking an agent to extend it. Battery-powered reporting is not a continuous high-rate data stream. Use the Gen3 instructions, not the separate Shelly BLU H&T route; security and reporting behavior depend on firmware.

3. **Build one useful behavior**: Start with a room-temperature history dashboard. Add logging, sensible timeouts and a manual off switch. Your automation runs on Home Assistant or another local host.

## Coding-agent project brief

Help me plan a room-temperature history dashboard using Shelly H&T Gen3. Read https://www.home-assistant.io/integrations/shelly first. Confirm my operating system, exact model, firmware and required accessories. Use only documented capabilities. Start with the smallest reversible test and ask before moving hardware, flashing firmware or changing credentials. Battery-powered reporting is not a continuous high-rate data stream. Use the Gen3 instructions, not the separate Shelly BLU H&T route; security and reporting behavior depend on firmware. Keep secrets out of public code.
