I use several of these handy little temperature and humidity sensors. I would like to have SmartThings integration but don’t know how/where to start.
Does anyone know if there is an existing device driver for this?
These devices use Bluetooth to talk to the phone but also have a Bluetooth->Ethernet/WiFi Gateway to get it on the cloud too. I have signed up for their developer program and have the HTTP API and used it to retrieve sensor data but that’s as far as I got.
Ever since SmartThings disabled their cloud Groovy SmartApp integration, the product is mostly dead as far as I am concerned. The cloud service is what made it thrive and be dynamic and interesting. That, coupled with the shutdown of the associated WebCore platform for cutom automations, totally gutted any useful functionality that SmartThings had.
But to answer the question, I don’t belive SmartThings has any SensorPush support
I recommend moving to Home Assistant (HA) which supports SensorPush. You would need to setup your own local HA instance but that can easily be done on a Raspberry Pi or old PC and even in docker. If cloud access is important to you, you can enable accee to your local instance via router port mappings or tunnels or pay to use their more secure, cloud-hosted service Nabu Casa.
