Read this completely. Basically anything that you can say to an Amazon Echo can be done with virtual devices, and done with custom actions. It can be a bit complicated, but if you read the whole thing, this can be a good step to getting it going with HE.
If you are a tinker-er and are not afraid to use a soldering iron or get a 3d-printed jig, there is a strong possibility to convert the Tuya devices via flashing new firmware to software called Tasmota. There is a Tasmota device manager in HE on Hubitat Package Manager to add them to HE. I know this paragraph is a lot to digest, but it works great. I have 58 Wifi Tasmota devices in HE, all 100% off the cloud, 100% local control, and flawless.
