WiFi Disconnected trigger

[mechrekt]

Since I work in a big area, I've several access points with the same ssid: can I use the wifi disconnected trigger using bssid instead of ssid to know if I'm in office or outside?

I'm not sure whether Android sends a disconnect event or not when you are switching access points within the same SSID.
You could also periodically check the BSSID using a condition WiFI Connected and a condition Expression: bssid=="11:22:33:44:55:66".
