Shelly Plug S Gen3
Generation 3 of Shelly Plug-S
At this moment there is NO way to Flash it OTA. You need to open the Plug and use UART!
As always, first take a dump!

This little seal need to drill open, best you use a prick punch with an M3.5-M4 Drill.
When the seal is cracked open, you need a M2 drill, and drill in center, just a little.
Now take a tapered punch and press the seal out. The whole grounding receptacle will come out.
We need some hot-air (~300°C) and 5 of the iFixit triangle-plastic, there are 3 spots with glue.
Heat them up, and try placeing the plastic around.
You will get a little gap, take anohter plastic and get betweet the white and transparent plastic, and make a circle.
After 2 rounds you can easly take it out.
