sorry for being late, first off the values you have requested:
WiFi signal strength: Good (-23dBm)
Bluetooth signal strength: Good (-60dBm)
My wifi router is TP-Link Onhub (google) router. It is placed in the same room as the bridge which is the same room where Bolt is attached to the door. I live in an apartment building (and there are many wifi signals (strong ones as well)).
Bridge has come back online and sometimes it works sometimes doesn't. I have sense enabled as well and that is working.
Next thing I am going to try is use the API to test if bridge keeps working or not. If you have better suggestions let me know.
