You rock, I wish most people were as informative.Well, here you go.

It is a mix of relays eating a lot (about 1W per relay), plus a bit power supply inefficiency.
To lower power consumption, you'd have to replace the relays, adapt the power supply (now: mix analog/switch via regular transformer + UA78S40) and driving circuit (now: ILQ30 quad opto).
And you'd have to replace the processor if you want more secure communications.
Can be done. Is it worth it? Don't know.
They are electromagnetic, thus represent a large part of the power draw (plus the inefficient darlington optocoupler drivers plus the power supply inefficiency). My guess is that most immediate gain could be had by changing the relays.The relays are solid state I suppose.
Yes, you'll need to vacuum the thing thoroughly if you want to avoid the smell of burning plastic later on.I have to admit the seller did go OTT with packing peanuts
I hooked up the ethernet port and used Wireshark to view broadcasts. Once I had it's IP I was able to change it via Telnet.Anyone know an easy source of the suitable cable so I can get into the thing and reset it, only want to get it onto my network so I can then use the nice lil windows app on it unless sd11 is right about being able to telnet into it and reset?
Mine arrived today as per others it has Left rack ear only but I have to admit the seller did go OTT with packing peanuts and I've opened up the power plug and it has 3 cables so going to rewire it into C14 so I can plug it into UPS in the future or whack it onto standard UK plug
