{"NAME":"Teckin SP27","GPIO":[56,255,255,255,255,255,0,0,255,17,255,21,255],"FLAG":0,"BASE":18}

Tuya-Convert might not be possible for this device since the template was added (2019-03-16). All new Tuya devices have firmware preventing flash but it is still possible to Tuya-Convert old stock devices without connecting them to the Tuya app.

NOTICE!!! Manufacturer has started using unsupported non-ESP8266 chips recently and this device might not be compatible anymore. Check seller descriptions or contact them before buying!

Warning: As of mid-November 2019, units purchased from Amazon.co.uk would not program with tuya-convert. Issue reported on the tuya-convert Github page as issue #394 https://github.com/ct-Open-Source/tuya-convert/issues/394

It appears that Teckin have changed the hardware and the new devices are using an RTL8710 which won’t work with Tasmota.
