The BlitzWolf SHP2, HomeCube SP1, and Teckin SP22 are basically the same device barring the branding.
There are at least two Versions of the SP22 out.
An old one with a TYWE2S WiFi module and ESP... chip. This version is compatible with Tasmota.
A new one with a WR2 WiFi module and RTL8710BN chip. This one is not compatible with Tasmota.
