Clarification: ppv/pgrid docs & writable #199
Comments
They can be written using ids/set in MQTT. You need to provide a json like this: with MQTT the endpoint is The uppercase letters are important. After the values have been written, ppv, pgrid and pakku will no longer be null and provide the values you have set with the ids endpoint. I have implemented this with Nodered today and was able to do a quick PV-only charge of my car. |
Hello Twiederh, I have some problems with this. Last Year there was no problems. But now I sent the values, I see the pgrid-value in the app, but the car doesn't load. Did you have any idea? |
Hi, Wichtig ist, dass pGrid als negativer Wert geschickt wird, wenn Überschuss da ist. Ich melde mich, wenn ich weiter getestet habe. Viele Grüße, |
Hi, vielen Dank für Deine schnelle Rückmeldung. Ich habe das negative Vorzeichen von meiner alten Version nicht mit übernommen. Daran lag es. |
Also ich habe das heute getestet, bis darauf, dass ich in meiner Logik in Nodered einen Fehler hatte, lief das Laden einwandfrei, es ist auch wohl nicht mehr so, dass am Anfang dreiphasig geladen wird, das Laden hat bei mir einphasig angefangen und wurde auf dreiphasig umgestellt. Ich muss noch an der Ladelogik arbeiten, sodass ich das Laden bei 80% stoppen kann aber das kann ich erst machen, wenn unsere Zoe wieder leergefahren ist :-) |
Super. Bei mir klappt es nun eigentlich auch - es lag an dem Negativwert. |
Ich ich habe zwei E-Autos, aber nur eine Go-E (aber auch noch zwei Tesla Wall Connector Gen 3). Ich habe mir für die GUI der Go-E in Nodered eine Dropdown-Liste gebaut, mit der ich einfach zwischen den beiden Autos (und einem Gastfahrzeug) umschalten kann. Damit beeinflusse ich die automatische Abschaltung bei einem bestimmten SoC, bei der Zoe soll abgeschaltet werden, beim Tesla nicht (der kann das intern). Das gleiche kann man dann natürlich auch auf die Ladeleistungen anwenden. |
what are the parameters you're using for PV surplus charging |
I do not work with the internal settings too much. I set pgt to -200 as recommended in the app itself, other than that I only send pPV, pGrid and pAkku. Since I have a home battery (Tesla Powerwall), I usually deduct 4600W from pGrid until my Powerwall reaches 90% to give it a priority, but this is configurable. Until the Powerwall is full I send pAkku with the value of 0. |
I'm setting the parameters within the app, pgt -450, single fase, prefer feed-in, 3f switching 7kW |
I configured my go-e charger to be on mqtt topic
I get a Also I tried:
What am I doing wrong? 😢 |
This is how I am using Nodered to have it working: I would try to leave everything as default, check, if a mosquitto client can read the values from the server the Go-E writes to and try to set the values with Nodered. Also: this is proven to work, why do you start with sending the values and not getting the values for the grid first and then work on sending them to the Go-E-charger? [ |
Turns out that I was on an old firmware - I did update, but apparently it only updated to an intermediate version and I needed to update again 🤔 This works now:
Interesting changelog entry I stumbled upon:
needs to be investigated 🤔 |
Hey there :)
First, thanks for openly documenting & making available an API for self-controlled Home automation 🎖️
There is some unclarity around how to tell the charger if (/how much) PV excess energy is available via API, instead of controlling charge state "manually" (meaning: via own software outside go-e app).
I've read in some places (e.g. this blog post or this comment) that the parameters
ppv
andpgrid
can actually be written to and used to achieve this.But the documentation is lacking any description and lists them as read-only.
Could you clarify?
