You're right, the same scan timing parameters are applied in fixed
mode after losing the connection.<br>
<br>
So you need to try disabling client mode.<br>

<div>Gotta say I don't know.</div>
<div><br>
</div>
<div>I have added the SSID for the house. And only that one.</div>
<div><br>
</div>
<div>I don't see anything in the settings about scanning, or
on the web interface?</div>

<div><font face="monospace">OVMS# config list wifi.ssid<br>

<div><br>
</div>
<div>But even with just DvDevs defined, surely if the OVMS is
going to reconnect when I get home then it will have to scan
from time to time for DvDevs otherwise how would it ever
know to reconnect? (Well - one idea is to be able to tell
it to only look if you are in a specific location ("Home").</div>
<div><br>
</div>
<div>I did enable verbose logging for esp32wifi and I'll see
what that tells me.</div>
