EHOT & Flower_power
Flower_power
Hey, I've been tinkering with a DIY sensor system for my compost pile—think temperature, moisture, and even a little solar panel to power it. Think we could make it smarter together?
EHOT
Sure, but only if you can keep the data clean and the code tight—no half‑baked scripts that eat the battery. Tell me what you’ve got so far, and we’ll see how to push it past “just a thermometer.”

Got a little Arduino board, a DHT22 for temperature and humidity, and a solar‑powered battery pack so it never starves. The code is all in one tidy file, no bloat, and I’ve set it up to send tidy JSON over Wi‑Fi to a cloud log I run on my old laptop. I even added a tiny LED that blinks green when the compost is in the sweet spot. It’s like a tiny garden guardian, not a hungry monster. How do you want to tweak the thresholds or add a little plant‑talk interface?
EHOT
Nice setup—quiet, efficient, like a compost whisperer. For smarter thresholds, let the sensor remember the last 10 readings and adjust the sweet‑spot band by ±5% each cycle; that way it adapts to daily swing. Add hysteresis to the LED so it only blinks when the temp is truly within range, not every 2 seconds. If you want “plant‑talk,” pipe the JSON to an MQTT broker and have a small Node‑RED flow that sends a text or a simple voice prompt to your phone when the composter hits the sweet spot. Keeps the system self‑sufficient and a bit more chatty.

Sounds super spry, love the adaptive band—like a living thermostat for my compost! Hysteresis on the LED will keep it from whimpering all day. And MQTT + Node‑RED? Perfect, I’ll be texting my soil like it’s a plant‑speak hotline. Let’s get this garden gossiping.

Nice, so you’re turning compost into a gossip hub—now that’s an upgrade. Just make sure the MQTT topic names are short, so the Node‑RED flow stays snappy. Once it starts text‑ing you about moisture, you’ll wonder why you ever stopped talking to your plants. Happy hacking.

I’ll keep the topic names as breezy as a leaf—short, sweet, no extra fluff. Then the Node‑RED flow can chirp back before the soil gets too dry, like a friendly sun‑kissed reminder. Thanks for the upgrade, I’ll keep the compost humming, the plants gossiping, and the sun smiling on us all.
