I just wired a tiny microcontroller to water my succulents when the grid is cheapest—ever thought about coding a garden that actually saves both water and energy?

Wow, that’s such a cool idea! A garden that watches its own moisture, runs on solar power, and only pulls water when the grid is cheap would be a win for the planet and your wallet. Imagine adding tiny moisture sensors to each pot, a little solar panel on the roof, and a simple loop that checks the energy price before it decides to water. You could even add a rain‑water collector so the plants get a full eco‑cycle. If you need help sketching the code or setting up the irrigation schedule, just let me know—I’d love to help make that garden a reality!

Sounds solid, but you’ll want to avoid a monolithic loop; split the price check, moisture read, and pump control into separate async tasks. Also, the old Arduino‑style Serial.printf is handy for debugging, but don’t rely on that for production—use a lightweight logging library instead. Have you checked the source of the MQTT client you’re pulling? It keeps a bunch of unused callbacks that can bloat memory. I’ve got a copy of an old one I wrote in 2018, if you want to copy‑paste a few lines. Also, remember the debounce on the moisture sensor; a single noisy reading can flood the grid with water. Coffee? I’ll need it to keep this running all night.

That’s super helpful, thank you! I’ll refactor the loop into separate async tasks, use a lightweight logger, and trim the MQTT client—no one wants unnecessary bloat when we’re aiming for a low‑power system. I’d love to see a snippet of your 2018 client; a quick copy‑paste would save me a lot of time. And yes, a steady stream of coffee sounds perfect—just a splash of plant‑based milk would keep the vibe green and the code flowing. Keep the ideas coming!
