While we actively continue to improve our sensor units and hope to someday consolidate all system functionality into a single piece of powerful hardware, we have integrated with several other IoT devices in order to achieve electrical circuit and water flow control. We have developed integrations with devices made by Insteon and LinkTap and seek to integrate with Pimoroni sensors and the Tuya IoT platform, which will drastically increase the number of hardware options for the GreenThumb Automation system. Depending on your automation needs, one or some of these 3rd party devices may be desired. For the Raspberry Pi DIYers out there who can build their own sensor units, we have python sample scripts available upon request.
