I bought a Treatlife DP20 plug in lamp dimmer from Amazon (https://a.co/d/9zlAsTq).

I was able to use the info from https://www.elektroda.com/rtvforum/topic4034434.html to flash the device.

I was able to get a working autoexec.bat:

There's a firmware backup on github for the DP20 which doesn't boot but we can extract the dpIDs from it still. From it we can see the DP20 has fewer compared to the DP10
