Show HN: A framework for Raspberry Pi pico projects

Developer AdrianCX released Picohive, a framework for Raspberry Pi Pico microcontroller projects that adds TLS, MQTT, Telegram, calendar, MCP and OpenAI API connectivity within 256-512KB of RAM. Picohive routes command classes dropped into a folder automatically via macros, and includes encrypted logs over UDP, encrypted and signed OTA updates, a web page and secure TLS; sample projects include an e-paper display, a robot arm and an irrigation controller. The developer posted the framework to Hacker News seeking feedback on its usefulness and ideas for additions.

Developing Raspbery Pi Pico projects is a very fun hobby for me

Ended up with something that makes my life much easier

Above lets me build projects that have tls/mqtt/telegram/calendar/mcp/openai API connectivity within bounds of a microcontroller (256-512KB ram)

All i need is to drop some command classes in a folder and some macros and they're routed automatically.

I also have encrypted logs over udp, encrypted/signed OTA, a nice web page, secure TLS and more

That makes projects like below pretty easy:

- [https://github.com/AdrianCX/picohive-robotarm](https://github.com/AdrianCX/picohive-robotarm)

- [https://github.com/AdrianCX/picohive-irrigation](https://github.com/AdrianCX/picohive-irrigation)

Looking for some feedback if it's useful, what else might be fun to add or build
