Ok, so this is the Hubitat forums so I'm confused if you are using SmartThings or Hubitat. There are a few different solutions:
- My original firmware meant for use with SmartThings or Hubitat (this thread). This is firmware I developed independent of Tasmota. I stopped development on it a while ago, but it still works with several devices (mostly older devices).
- A modified Tasmota that I created to simply add instant status updates from the Tasmota firmware so that Hubitat or SmartThings knows what state it is in and gets instant updates regarding temperature, energy usage, etc. Tasmota had support for so many devices I figured this was a better solution than trying to keep up with my own firmware.
- A modified Tasmota created by @markus. He pretty much took over this project and has done a great job on making releases for the newer versions of Tasmota. His thread is over here: [Release] Tasmota 7.x/8.x firmware for Hubitat + Tuya, Sonoff and other drivers
Since this is a Hubitat forum the specific instructions and information here is geared towards that platform, but most of this stuff can be used with SmartThings with a few tweaks (not sure which platform you are using).
