Smappee power meter integration?

---

Hi everyone.

I was wondering if anyone already has or planning to add support for the smappee power meter?
I’m not at programmer, but the information i have found suggests that it should be possible to make some kind of plugin that retrieves the data from the smappee on the local network.

https://grunenberger.net/2016/02/16/smapee-device-api/

Or else perhaps through the smappee API?

Is anyone, with the skills, able to say if this is possible, and how difficult it would be for a non programmer to do?

Hope you all have a happy new year.

Kind regards Simon

Writing a plugin is easier than you think if you have any basic programming skills. Looking at the Shell script you linked to it looks quite easy. Otherwise you could use the Shell script combined with the LogReader

Thanks for the reply.

No skills at all hahaha, but maybe I can find some guides on how to do it and give it a try if no one have done it already. Would rather not have to spend months on something I have no idea about if someone else already has, but otherwise I will give it a try in a few weeks, but it would be a nice addition to pimatic to have the power consumption directly in the gui and be able to control devices with the input from smappee. It is a very clever device that can detect when something switches on or off.

You can start with modifying the shell script and make that work. You probably only need to remove the references to Domotics in the script to get a plain text output of the script

@simonbove It’ll be very helpful if you can the execute the basic curl commands at your end and post the responses you get.

curl -X POST -s -H ‘Content-Type: application/json’ http://[YOURSMAPPEEIP]/gateway/apipublic/instantaneous –data ‘loadInstantaneous’

# if you also have a Chacon power socket please also try the following

curl ‘http://[YOURSMAPPEEIP]/gateway/apipublic/commandControlPublic’ -H ‘Content-Type: application/json’  –data-binary ‘control,controlId=0|1’

curl ‘http://[YOURSMAPPEEIP]/gateway/apipublic/commandControlPublic’ -H ‘Content-Type: application/json’  –data-binary ‘control,controlId=1|1’

I tried with the first command. And it opens a connection, but no output in my terminal.

It might be my connection though, as I’m on a ship with a crappy satellite connection and I’m not home before in a couple of weeks, where I have a proper connection.

@simonbove Seems like these devices require a simple logon procedure.

Please create a shell script (assuming bash here) as follows:

#!/bin/bash
# Replace <YOULOGON> with your local admin pasword. If you haven't set one use "admin"
# Replace <YOURSMAPPEEIP> with the local IP address of your power meter device
curl -H "Content-Type: application/json" -X POST -d "<YOULOGON>" http://<your smappee ip>/gateway/apipublic/logon
curl -X POST -s -H ‘Content-Type: application/json’ http://<YOURSMAPPEEIP>/gateway/apipublic/instantaneous –data ‘loadInstantaneous’

It is logging in successfully, but still no output from the second curl command. Just leaves the connection open, which I then close after 10 minutes of waiting with control C.

pi@raspberrypi ~ $ curl -H "Content-Type: application/json" -X POST -d "admin" http://192.168.3.12/gateway/apipublic/logon

{"success":"Logon successful!","header":"Logon to the monitor portal successful..."}pi@raspberrypi ~ $

pi@raspberrypi ~ $ curl -X POST -s -H ‘Content-Type: application/json’ http://192. 168.3.12/gateway/apipublic/instantaneous –data ‘loadInstantaneous’

^C

Another curl command gives me the following. So it does work in some way, but just not with the above command.

pi@raspberrypi ~ $ curl -s  http://192.168.3.12/gateway/apipublic/reportInstantaneousValues

@simonbove This looks very promising! Can you please also try the following which sets an additional header field?

curl -s  -H "Accept: application/json" http://192.168.3.12/gateway/apipublic/reportInstantaneousValues

Found some additional information here:

Don’t see any difference with the command below. So to get total power consumption at this instance one would have to add all 3 phases together with some logic. I don’t know if that is possible in Pimatic? And to control some stuff, we would also need some logic, to say, if power goes above 200 watt then someone is at home for example.
Or turn off tumble dryer if power goes above 4000 watt on phase 2 - to avoid the fuse busting.

But the local API is very limited from what i can see. We can see the consumption on each phase, and that is more or less it. To get the clever knowledge from smappee, about which appliance have turned on and off, we would need to use the API from their server and not locally, or just simply use the slow IFTTT function, which i do not like.

You can do simple Calculations in Pimatic. For your overall power you can simply add Power1 to Power2 and 3.
For more complicated stuff you can use Node-Red (but don´t ask me how )
Maybe you can calculate the same things like Smappee(which appliance is on…) I don´t think that they get more information then you, out of the api.

Things like your tumble dryer example are no problem if you can get the values.

The api tells: phaseshift=0.0, phaseDiff=0.0, is this correct?
In Germany we have 120° between the 3 Phases.
Or are you measuring in 3 places but on the same phase?

I live in Denmark and we are using 3 phases and not only 1 like the US (from my understanding). Smappee is using, from what i know, not only the wattage from a appliance, but also some other parameters to guess which appliance that is on. But i don’t think i will even be able to come that far, i’m just hoping that i can figure out how to import the consumption data into pimatic, so i don’t have to use the smappee app. That will be a success for itself for me, since I have no programming experience.

But yes there should be 120° between the 3 phases.
The API have the phaseshift=0.0, phaseDiff=0.0 but i do not know what they should indicate and when they should change value.

Maybe this can help.
If you use MQTT you can use it directly.
If you don´t, maybe someone can use it for a plugin

Yes! That is exactly what I need. Thank you for the link. I’ll give it a try in a few weeks time😁

I looked at Smappee, while browsing for some power meters, and initially it seems nice. Lots of similar devices exist, like Neurio, Curb, Aeon Labs Power Meter, Zipato Power Meter. However, the Smappee also has gas & water meter devices, which makes it interesting.

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.

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 ?

I love smappee. I have now used it for more than two years with no problems. The android app is working good. No idea about ios app. The data collection is good, although with any free service they have reduced their costs by limiting the data stored over the time, the longer time passes the less data you have available online. But you can save it manually if you want the hourly data many years back. The only problem I have had is with the distance from my water meter and electric meter, I have had to make my own antenna to pick up the signal from the water monitor.

In the beginning I also needed a bit of help from support at setting up the correct settings for my local installation to get accurate readings, but they were very helpful and it was solved in a few days.

The only thing not working that great is the ifttt, it is slow, but I don’t think it is smappee fault.

The readings are very accurate, they match my electricity company hourly readings.

The reason I want pimatic support is to have all data at the same place, so I don’t have to use 10 different apps to control my home. I want a all in one solution 😁

Could not get the MQTT script to work. Some JAVA errors which i don’t understand.
So now i am moving on to something else I have found:
http://www.loxoneforum.com/tag/smappee/

Looks like it will create a PHP file, which i then hopefully can grab using the log reader plugin.

We will see if I can figure it out. Otherwise maybe there are something from here I can use: https://github.com/mortenf/smappee-tools

If anyone have some clever inputs. Feel free to write a comment

Also, how do I make a dummy power meter? Can not find the device in Pimatic.
