I have been looking for a way to measure 20 to 60 vdc and get the data wireless into a home local area network.
I looked at handheld DVM's with usb and bluetooth but was hoping someone might know of a relatively inexpensive way to do this.
Keysite has an IR device that works with their dvms.
Thanx!

    Mooshimeter
     https://moosh.im/    (yes, it's an odd looking link, but legit) is a Bluetooth remote meter,   It measures and broadcasts to a paired low power BT3.0  device.   That gets it to my new phone.   The app on the phone displays everything.

    googled this...   http://www.digital-measure.com/

    Should be able to find a bunch of things in the SCADA / PLC world as well, but they're going to be pricey.

    I'm sure someone's got a raspberry pi out there doing it too.

    Fluke has wireless meters but limited to the receiver and "thru" an android/iphone to the outside world. Not something that would live on the network full time.

    The One Laptop Per Child XPC included an application that used the audio input as a voltmeter and broadcast the results to other networked units running the same app.
    Not very accurate, but dirt cheap at the time.
    SMA SB 3000, old BP panels.

    Mike's link is the perfect solution and if they just can stay in business. Hey Mike, was there any info with the unit that might indicate how easy it would be to use the  DC voltage readings and control another Bluetooth device?

    No idea, never tried it.  But if you get the BT 3. into a laptop or desktop, the ethernet is right there

    Thanks Mike.  I also found a Fluke version of the Moosh for twice the price which made me a bit more confident that it will be there.
    I am trying to get the voltage data to throttle back a mini-split when clouds come in. I am trying to do this without using MODBUS data from a COMBOX.  I would really like this to be usable with Outback or even some kind of grid-tie scheme.

    So you are saying use the ethernet, please explain?
