Solar Heaters (3 different boxes that were a science project) are connected in series and are being used as a supplemental heat source for my bedroom. I am using 4 DS18B20 sensors, 1 DHT11, a servo, and 3 fans. These are all being controlled by NodeMCU.

This is data showing water level and volume for a reservoir. Reservoir devices are off the grid (no power, wifi) and use ESP32 (NodeMCU-32S)/Moteino Mega with JSN-SR04T sensors and Lora (Reyax RYLC896) to send results. Solar + 18650 LiPo bat for power
