[BETA] Echo Speaks V4

Hi @tonesto7,

I've read in some places that I could identify which Echo device was used to send a command to HE using some of the device's properties, like "lastSpokenToTime" or "wasLastSpokenToDevice".

However, those properties aren't being updated at all - nor are some other "activity" properties like "lastSpeakCmd", "lastVoiceActivity" and "phraseSpoken". Sending the "getDeviceActivity" command doesn't affect them at all, even after waiting a long time.

I've reinstalled the Echo Speaks app but I haven't recreated the devices yet, since it would break some rules - I'd like to wait for any input from you before doing so.

Thanks in advance !
