I recently discovered a supplier of 3D printed enclosures for TTGO LoRa32v2 microcontroller development boards, and bought a couple. I have used a red one to give a completely new appearance to the LoRa link indoor receiver module. These enclosures are also available in black and dark blue.

Having also upgraded the firmware, I am now uploading moisture data both to the Ubidots cloud and, simultaneously, to Thingspeak (see a previous post) without the Node-RED server.
From my Ubidots dashboard I can remotely turn on/off a green LED ( see image above ). This feature could be used instead to control a solenoid valve for an automatic watering system.
