You may be able to interface it with a meter, if you have a way of converting the signal from a meter so the ioio can read it you should be able to make the app.
I am currently working on a project that implements this but a bit differently using a watt meter and amp meter

根据 http://en.wikipedia.org/wiki/Automatic_meter_reading 有许多不同的类型和这些无线仪表使用的协议可能是专有的实现。
有些甚至可能包括加密或校验和验证的协议，这将进一步阻止读取数据。
这是个好主意，但如果没有提供抄表技术的公司的官方支持，您可能会运气不好。
As per http://en.wikipedia.org/wiki/Automatic_meter_reading there are many different types and likely proprietary implementations of the protocol used by these wireless meters.
Some likely even include encrypted or checksum verified protocols which would further prevent reading the data.
It's a good idea, but without official support from the companies supplying the meter reading technology you are probably out of luck.
好吧，你可以让用户给仪表拍张照片。然后你可以分析图像......
Well, you could make the users take a picture of the meter. Then you could analyse the image...
你看过 ioio 吗？
您也许可以将其与仪表连接，如果您有一种方法可以转换来自仪表的信号，以便 ioio 可以读取它，您应该能够制作该应用程序。
我目前正在开发一个项目，该项目实现了这一点，但使用瓦特表和安培表略有不同

Have you had a look at ioio ?
