I have a go-e charger Smarte Ladestationen für Elektroautos: mobil & stationär | go-e and want to make a homey app for it. So far I can add the device from a local network and use homey to read it’s values: [image] GitHub - phatenl/nl.phate.goecharger Contribute to phatenl/nl.phate.goecharger development by creating an account on GitHub. Now I want to take the next step, actually setting values through homey. I’m puzzled though on how to do this. Is there a simple example available somewhere? The dev documentation is a little cryptic for a starter like me. Which app would you recommend for me to review the code of, to learn from? Many thanks in advance!

For a longer period the measurement of voltage was showing 1V in the device and in the measurement tags in Homey. Though the android app showed the correct value. I figured out today what was wrong. My charger is connected with 1-phase schuko socket. When I “switched” the schuko other way around the voltage measurement “healed” itself. Apparently the charger measures the voltages compared to the earthing, so when you switch the plug it shows the voltage in L1-phase or in N-phase. This is also explained in the API documentation and there is also solution how the 1-phase voltage should be presented. Haha it’s been a year before I have the time to look into this. The whole pha/8 kindof thing really puzzled me at first. And I’m still not sure what the “before and after the contactor” thing means. But I do see the problem now. I’ll try to figure out a solution and come back to you. Unfortunately I cannot just copy the code example from the API into the app :slight_smile:

Blockquote Would it be possible to add more accuracy to the total energy consumption (eto). The api documentation says it should be available with 0.1kWh resolution. I’m not sure how. The value is in tenths of a kWh. i.e. “130 means 13kWh charged” I only divide by 10 to get to actual kWh. But this does not mean it’s getting less acurate, only the position of the decimal is moved to the right place. I won’t be solving this, sorry. Still looking into the whole reversed voltage though. :slight_smile:

That’s ok. I thought that some rounding is made in the Homey app, but the accuracy from the go-e device itself is as accurate as it can be. So it changes on 10 increments 10->20 = 1kWh->2kWh.

I changed to three phase connection so it’s not needed on my behalf. But if you make some change I can help to test it though.

Hello, I have 2 go-e chargers at home. I have problems managing both with Homey. For example, I am not able to : check “car plugged in” in each charger set stop/allow-charging only for one charger receive notification "charging How do you deal with this ? Thanks and regards, Paul

Exactly. The next step in Tim_Willemsen’s agenda is to make it possible to switch between single and three-phase charging with the Go-e Charger app! I guess so :wink: (this comment is followed by a short silent prayer)

Do you mean that when you add two go-e chargers these actions and status are mixed for both chargers.

Hello, yes , the actions are mixed between the 2 chargers. I found a way to partially fix the problem. I am using HTTP request flow cards and sending the following commands :slight_smile: adjust amps curl “http://1.2.3.4/api/set? amp=16” #set 1-phase curl “http://1.2.3.4/api/set? psm=1” #set 3 phases curl “http://1.2.3.4/api/set? psm=2” #start charging curl “http://1.2.3.4/api/set? frc=0” #stop charging curl “http://1.2.3.4/api/set? frc=1” Details regarding the API are there : go-eCharger-API-v2/http-en.md at main · goecharger/go-eCharger-API-v2 · GitHub goecharger/go-eCharger-API-v2/blob/main/apikeys-en.md [Deutsch](apikeys-de.md) • English # API Keys | Key | R/W | Type | Category | Description | | ---------- | ---------- | ---------------------------- | ------------- | ----------------------------------------------------------------------------------- | | rfb | R | int | Status | Relay Feedback | | rst | W | any | Other | Reboot charger | | alw | R | bool | Status | Is the car allowed to charge at all now? | | acu | R | int | Status | How many ampere is the car allowed to charge now? | | adi | R | bool | Status | Is the 16A adapter used?

Would be nice if @Tim_Willemsen would have the time in some point to fix this. But luckily one can use the http requests or the mqtt api.

I’m sorry, I’m afraid the only way to fix that is to redesign the whole app. Right now that’s not on my agenda.
