TYWE3S

[KevinW]

I have a model 70011 Intertek Sharper Image smart socket that belonged to my daughter in law.
It quit working for her so I took it home to look at it.
The set up seems to be working properly.
It manually switches but it won't sync with my wifi at 2.4 GHz.
The TYWE3S is receiving 3.3 volts, is there a method to test other pins in order to prove if the TYWE3S is actually working or maybe needs flashing or replacing?
The module I have doesn't have the test point.

That's a good link for the manual.
I have the app loaded and the everything works up to the point where it won't connect to the wifi.
Switch and lights work, starts to connect to wifi and then fails.
I was wanting to prove if the TYWE3S is defective.

Is your router set to connect to a. 2.4GHz device. Some routers have settings to force 5GHz only.
Or, does your router allow connections to older 802.11b protocols.

Alternatively, the website that acts as a bridge between your phone's app and the device is now defunct. Several of these device manufacturers have discontinued support because of the overwhelming effort to stay ahead of hackers to maintain security.

These same outlets have been labelled with "sharper image", "craftsman" and "kobalt" brand names (likely others as well). They are made in China and programmed by the manufacturer to ping either the manufacturers website and app or the licensee's website and app.

This is what I get when I give them the model number and inquire if the app still works.

Look for ripple on its power supply reservoir cap? (First one after the input rectifier).

One of my z-wave switches failed after a couple of years and it was a fault cap, causing excess PSU ripple.

I had replaced both caps near the bridge rectifier, that's what I thought it might be too.

Again, as in your other thread, the most likely culprit is a capacitor on the secondary side - easily tested with an ESR meter. Reservoir capacitors do fail, VERY occasionally - probably less than 1% of cases (as they aren't subjected to the same switch-mode 'abuse' as the others).

You could try converting it to an ifttt device - it appears to be a simple ESP-12F module (based on ESP8266). You can try to directly upload code from the various IFTTT libraries and examples. Or, you can change the module and upload the new code to a new module to improve the odds that it works.
