Wiser Heating Disconnects After Pairing [Fixed]

[Littlepanda115]

Good afternoon,

I have a Wiser heating system installed for my boiler. Worked a treat, but recently I switched broadband provider to Vodafone.

The app seemed to expect something like this, and guided me through a process to join to the new network. I clicked setup, and it flashed green. I joined the new LAN it made, and continued in the app. I selected a 2.4GHz WiFi connection of mine from the list, and put the password in. It connected for a bit, then succeeded, and I got a green tick and could see the dashboard.

Then, it closed the LAN, and my phone switched back to my WiFi. The dashboard then lost connection, and the Wiser hub's flashing green went straight to red. It is inaccessible through the app now.

I've repeated this on 5GHz network, 6GHz, etc., etc. I can repeat the setup time and time again, and I've tried powercycling the hub with 10 seconds of power off.

Every time, it shows me a green tick of successfully connecting - I can even see the new network name in the device settings in the dashboard on the LAN hotspot it provides.

The moment that LAN hotspot closes, though, the LED goes static red and I can't connect to it...

I've left it in this 'configured' state for a good while (2-3 hours), and not gotten any access, so I don't really feel like it's just 'setting up'... The app oddly doesn't seem to offer any WiFi configuration details when on the LAN hotspot, either, so it's hard to troubleshoot. I can just see it has the correct network name in there, though it does recognise it isn't connected properly. I just can't then actually do anything about it, hah.

This is all setup on the Drayton Wiser Smart Multi-zone Kit hardware bits, if it helps.

Any ideas...? The device having just one button makes this a little difficult, hah...

Well, what do you know. I'm not the first. Looks like the issue is Vodafone's 'compatability mode' does not actually do 2.4GHz only, it does at the least 2.4 and 5.

For anyone who finds this problem, you can get around it by:

Renaming your compatability mode networking (say, 'CompatNet_Temp') on your Vodafone hub

Using your mobile phone to open a 2.5GHz HotSpot named what your compatability network used to be (i.e., 'CompatNet'), and be sure to use the same password and WPA2 security.

Use a 2nd mobile device to configure your Wiser hub to use the HotSpot.

Rename your Vodafone's compatability network back to the original (i.e., 'CompatNet', so removing '_Temp')

Disable your mobile hotspot

This means the Wiser joins the hotspot with the correct credentials, and fully connects up. You then overlap the two networks and remove the hotspot. Wiser then connects to the Vodafone network with the right credentials and already on 2.4GHz, no need to negotiate.

Bish-bash-bosh.

I guess this is Vodafone's fault more than the product's. Pain the rear for sure. Consider this closed.
