Should anybody please send the information in order to create a sketch in Arduino for sending alarms to Smarthings? I mean the connection protocol and the connection information.
Thank you and best regards
If you’re wanting to develop an integration using the newest, ST API, then please take a look at the following explanation from @jody.albritton for building direct-connected devices. This solution does not require a ST hub at all. Your microcontroller would talk directly to the ST Cloud API.
If you have a hub, and want to incorporate Arduino-attached sensors and actuators with SmartThings, you may want to take a look at my ST_Anything project. But be forewarned, the ST Groovy IDE will be going away some time in 2021. I have no idea what that will mean for ST_Anything as it currently relies on the Groovy DTH model for its integration.
