How to tell if the flash will work beforehand?

[franco-giordano]

Hi. So, basically, I have two Tuya light bulbs ("Teckin" brand), which I've bought around January 2019. I understand they may work because they should be running the old firmware. Before accidentally bricking my devices I'd like to check whether the flash will work, or if they are indeed using the old firmware.

How can I check this beforehand? Is there a way to inspect the protocol/firmware version via Wifi or something? (e.g. TuyAPI)

For reference, when using TuyAPI, I need to set it to protocol version 3.3. I've checked previous issues, discussions and the wiki but found no info regarding this.

Thanks!

+1 would want to test to see if my devices are supported as well.
