Enclosure for WT32-ETH01 + 4x Relay's + DS18b20 The enclosure gives a snug fit for the WT32-ETH01 + Relay board there is a cable clamp for the relay connections, there is also clamp on the supply cable, this could be printed in TPU, the lid has a lip which locks onto the cable entry. There is also an additional entry which I use to connect several DS18b20 temperature sensors. thus this device can act as a highly flexible thermostat control using Letscontrolit firmware WT32-ETH01 is a ESP32 chip with the benefit of an ethernet interface. purchased from Aliexpress.. https://www.aliexpress.com/item/1005001556914151.html?spm=a2g0s.9042311.0.0.8e554c4dQEtGuc 5v x 4 Relay Board https://www.aliexpress.com/item/1005001714620325.html?spm=a2g0s.9042311.0.0.27424c4dwtDgRZ I use the following firmware.. https://github.com/letscontrolit/ESPEasy/releases/download/mega-20210114/ESPEasy_ESP32_mega-20210114.zip To flash firmware GPIO is held low. Connect using a usb > serial connecting to TX0 and RX0 I used the included Espressif_flash_download_tool_v3.8.5 see https://www.letscontrolit.com/forum/search.php?keywords=wt32-eth01&sid=33dfd05c6101d2baed601d9dd276baf3 for more information and ethernet settings. I initially connected 5v supply directly in parallel with the relay board, however when repowered this caused the ESP32 to hang, I then connected the relay board with a diode and this solved the issue.
