The roaming scan found two APs for the SSID every 10 minutes but the log
never showed their signal, so there was no way to tell whether the
device at -70 dBm had a better AP to move to. Log each AP on the
roaming scans, show roams at info level, and switch for a 6 dB gain
instead of 10.

At -70 dBm the RSSI moves a dBm or two constantly, so the >1 dBm check
every 1.5s sent wifiStrength to every client about 270 times an hour.
That is extra traffic on an already lossy link and a state write in
Home Assistant for each one.
Broadcast on a channel change, or for a change of at least 3 dBm no
more than every 10s. A newly connected client still gets the current
value straight away.
