A DIY General Purpose WiFi (IP) Based IO Module for Ezlo


Picked up a handful of ESP32 minis and hermetically sealed DS18B20 temp probes $9.51 for the both. Added an old USB charger and a cord and I have a WiFi based temp probe. Just loaded my IO Module Arduino code on the ESP32 but only the temp probe portion is getting any usage. The probe with a cord is needed because the ESP32 has a heat profile that throws off the temp reading if the sensor is within 10" (250mm) of the ESP32.

It is polled by Ezlo Plus from an IP Device template. Works flawlessly. I like having an IP Device rather than a peer EzloPi given my preference for the controller (Ezlo Plus) to be the master and the device the slave.
