I purchased this board and tested on my printer. Updating and flashing firmware is a never-ending process, no proper documentation, We don't know whether updates and printer necessary settings have flashed to the board or not, it may be working for designers printer but not with all. Not recommended, stick to Octoprint if required you better upgrade you printers motherboard to make it usable with Octoprint.

No documentation but it seems to work as advertised.
The only documentation provided was in Chinese, and even Google couldn’t help me translate that. So I had no idea how it was all supposed to work. However, the two pieces (detector and outlet) appeared to have already have been paired. When I test the smoke detector, it does shut off the outlet, so it seems to work OK. I found a comment online from the seller (on Thingiverse.com, which is where I first heard of the device) saying how one could re-pair the system if needed. It wouldn’t have taken much to provide either some English documentation in print, or at least a link to a .PDF file online. But the bottom line is that it seems to do what it’s supposed to do. So I guess that’s what matters.

Hi Ronald, thank you for your comment, this made me decide to do better and write a manual file in the package.
