botmonster @botmonster.com · Jul 2 Monitor every houseplant for under $10 each: one ESP32 running ESPHome 2026.3.0 reads capacitive soil moisture, a BH1750 light sensor, and temp/humidity for a 4-plant hub. Just buy v2.0 sensors, not v1.0. What's killing your plants, under or over watering?

Buy v2.0 capacitive sensors with the onboard regulator and NE555 chip. v1.0 boards corrode where moisture wicks up the exposed traces. https://botmonster.com/smart-home/build-plant-monitoring-system-esphome-soil-sensors/?utm_source=bluesky&utm_medium=social #SmartHome
