Smappee energy monitor

Are there people here who use Smappee energy monitor (www.smappee.com) and can make a app for it?
there is a API https://smappee.atlassian.net/wiki/display/DEVAPI/SmappeeDevAPI+Home

I'm going to have a chat with the smappee guy's to see what there working on and give them feedback of our experience. But for now I scrapped the smappee of my work and home project lists since it just doesn't work good enough to really use it.
I really hope smappee to become a really solid product! It has lots of potential. But I guess I will find that out soon. Maybe will post an update here after the chat.
The API is also quite easy, so building an app wouldn't be that much work.
However, I have read that it is (was?) buggy, especially the mobile app, etc.
@AcE_Krystal: could you elaborate where it's unstable, is it the mobile app itself, or the readings ?
Have you checked out the latest updates, has it improved ? Or did you completely ditch Smappy ?
Smappee is missing a lot of devices going ON or OFF what makes it basically "okay" for reading the total energy flows in your house but for a bit of a high price. The problems that I found when testing it in 3 different houses are:
- Seems it does not pick up devices with a power consumption of less then ~40 watts increments ever ~3 seconds.
- It measures if devices are ON or OFF by also looking at the amount of increment or decrease is watts used. This means if a devices uses 1154 watts, it will recognize when the current energy flow is increasing or decreasing by ~1154 watts. (it seems they also do a bit of startup and shutdown patern tracking). But it isn't solid enough to deal with for example a pc using 1000 watts on startup (500 watt for PC + 2x 250 watt for screens), but when shutting down giving directly a -500 watt, and ~20 seconds later the screens go in sleep mode giving they other -500 watt. Smappee will not know that this is the PC of 1000 watt turning off.
Also you need to spent a lot of hours to deploy/teach smappee your devices in your house. Only your refrigerator has already like 9 different power consumtion states, that will show up as 9 different (but very close) un-named devices that you need to figure out this is your refrigerator.
At the moment I'm just using the P1 port or pulse counters combined with a RBpi (OdroidC1+) and some python scripts. But I'm still looking around for a cheap way of monitoring all electronic devices in a home.
Maybe a developer?
Did you get in contact with the smappee guys?
They just might send you one FOC...
