My greenhouse automation rack
Been running this for 3 months now. Full ESP32-S3 based rack with:
- DHT22 for temperature/humidity per zone
- Soil moisture sensors (capacitive, 4x)
- 8-relay board for irrigation valves
- OTA updates via Plynx dashboard
Dashboard setup
Using 3 tabs: **Overview** (gauges, trend charts), **Irrigation** (relay control + schedule), **Alerts** (threshold config).
cpp
#define BLYNK_TEMPLATE_ID "TMPL..."#include <BlynkSimpleEsp32.h>void setup() { Blynk.begin(auth, ssid, pass, "plynx.cc", 8080);}Anyone else doing soil moisture with Plynx? Found the V5 virtual pin read rate to be a bit slow for real-time irrigation decisions.
