    Default Electrisave/Owl Protocol + PC Interface

    I am looking to build an Electrisave to PC Interface for logging and found in the archives an interesting post from Iain Goodhew (16/1/2007) who said that he had reverse engineered the protocol. Did any more come of his project ? Does anyone have his email address ? He did ask whether anyone was interested and I would be ?

    Otherwise I know that I can buy an RxCom receiver but this is 'over the top' for what I want to do. I envisaged hacking the Electrisave receiver to recover received RF data, decoding this (with a PIC) and outputting via RS232 - but if this has already been done ????

    Take a look at the the CurrentCost units - they have a serial interface on them that spits out the data at 4 second intervals in XML format. The interface requires their special cable to connect to the PC as it does level shifting. It's well priced too at around 40 ish

    K

    PS I'm told that some OEM variants of this don't have the inbuilt serial circuitry.

    Default Current Cost - Costs How Much

    Very nice looking unit. Web site provided a lot of information apart from the 'current cost' ? Perhaps this is available from distributors only ?

    Interesting ... good to see they quote example accuracies (the more current the better teh accuracy, it would seem) ... does it measure the voltage, too, or does it just measure current & make assumptions about the voltage, I wonder ? And how much does it tie the PC up ?

    Contacted Current Cost and the guy I need to speak to is on holiday, so should hear from him at the end of the week.

    Thanks!! 33 posted, bargain! Order placed.

    What's up with 9 quid for a straight RJ11-RS232 cable though...

    Default Hmm - Not as easy as I thought !

    Not quite as easy as I thought ! Got all the 'bits' OK but decoding the packet structure is not obvious

    Anyone got an email address for member Iain Goodhew ?
