 Post subject: Anyone Tried Using A WD PiDrive?

After actually getting my standard Pi to work I noted the slow sampling rate and other constraints caused by writing all the data to a Micro-SD card.

Anyway, Western Digital now offer small hard drives with a provided Micro-SD card to boot the drive.

Has anyone tried this with their energy monitor?

I have ordered one...

250GB Western Digital PiDrive - Foundation Edition

Hopefully then it should be possible to increases the data sample rate and get accurate daily energy consumption figures.

Time will tell...

We have a Raspberry Pi running a version of our DashBox with a portable HDD. It works pretty well.

If you're using an RPi 3, make sure you use a 3A+ 5V power supply as the Pi is power hungry.

All my bits finally arrived and not 100% impressed with the WD 6" case which on the rear exposes the PCB's of the Pi and the Hard Drive to damage.

In my btmon.cfg I have set oem_upload_period = 0 which makes the inputs web page say updated typically staying at 1s but sometimes up to 5s

So I guess still not real time :(

System at present says

Total: 923.35 MB Used: 180.64 MB Free: 742.71 MB

It will be interesting to see if the data is being stored on the hard drive.

The PiDrives are being discontinued and the prices appear to have dropped.

I bought a 250GB drive with the special USB cable and preloaded micro SD card for $23.19 and later bought a 6x6 case for $8.79.

Both orders were less than the listed $50 minimum for free shipping, but no shipping charge was added.

Yes, there is a cutout in the base of the 6x6 case under the edges of the pi and the drive, but is about 7/8" by 1 1/8" and doesn't bother me. So far, I'm pleased with purchases.
