Smart Devices not staying connected or "no data"

[Midori47]

Recently I got two smart devices which do not work.  1 is Schneider Drayton Wiser 3 Smart Home Hub with 2 x w/l thermostats. The other is the Smart Doorbells (two of which I failed to get working).  So Smart objects have won 3 nil against me.

Both Mobile App setups ask for their devices be connect to my router (no password necessary) and both connect but with a "no data available" mode. Then setup asks to revert the Mobile back to my regular router SSID instaed of the Device SSID. I guess this is same for all smart devices to act as a server to the mobile phone.  

I have checked in both cases the same WiFi1 (or Wifi2) are adhered to. The Doorbell does state a requirement for 2.4GHz and "Inteligent WiFi" to be enabled on my Phone.  The Wiser 3 makes no qualification on GHz.   I have the latest Vendor App firmware too.  I also read the 2023 forum post on similar issues and checked WiFi channels, though  2.4GHz does not show my router or my devices at all. 5GHz ditto. 

I am assuming it has to be the intellligent WiFi services not being intelligent enough for both smart devices, but that is beyond my knowledge.

I've only set up one Drayton Wiser hub, I don't have access to that network now, and that was probably more than a year ago.  I had a quick look at the installation videos online just to double-check, and it really shouldn't be that difficult.
*I'd never have installed the Netatmo system I have, if these had been available at the time, as while the software is near identical, the installation would have been so much easier (though I would never have picked up on the bad wiring in the service cupboard).

Agreed 100%_________ "it really shouldn't be that difficult."

Thanks to all for your support. I have since spent (wasted) the past 3 days working with Schneider-Drayton the reseller of this product. There support was pathetic and their response over 10 or more emails was simply to repeat the setup instructions. They refused to do a live Zoom, and today I asked to be sent their 'Return Authorisation Form' for a full refund.  So this matter is now closed and thanks for your patience. 

There is a 9 minute video I sent them showing my full process start to finish but the supplier could only reply "Repeat the set up procedure".  If you wish to see the video I can put a share link here - but frankly perhaps better to give up.
