And here we are, later in the afternoon when the sun has become too weak to continue charging my EV from solar power...

All the sensors in my Pulsar Plus seem to read between 5 and 10% low compared to what my solar power system says. For example, the peak charging power reported by my Pulsar Plus is 3.1kW whereas the Redback Solar Power system reports about 3.45kW. Similarly, the voltage reported by my Pulsar Plus was in the low 220s when I was charging my EV last night whereas the Redback charts showed 241V. At present, with maximum power of 3.5kW being exported, the Redback reading is 243V. In common with all AC EV chargers, there is no reporting of SoC through the vehicle connection. When we come home from a day's driving, I make a mental note of SoC and then work out how many kWh will be needed to get back to 80% or 100%. If we're driving again the next day, it will sometimes be 100%, depending on how far we're planning to go. Otherwise, if we're not planning to go anywhere for a while, I leave the EV sitting at around 80%. For me, it's a very simple equation: % SoC gained = kWh x 3.3. Where kWh is as indicated by Pulsar Plus, so in reality reads a bit lower than it should do. |

If your vehicle is supported one of these can be useful (fun to tinker with) to get metrics on the car/battery https://www.openvehicles.com/ |

Thanks for the tip. I see there is a cable specifically for the Nissan Leaf, so I can't imagine it wouldn't be supported, as the first mass-produced EV. Another idea to investigate when I have the time 😄 |

Yes it is. I've extended the ovms code to support my 2016 AZE0 and V2H, and another NZer contributed to the ZE0 support. |

Do you have a V2H inverter installed yet? |

Now I have some additional nodes working...
Meaning that the 'Set Max Current' slider in my dashboard communicates all the way through to the Wallbox App and charger. It was a lot harder than it should have been due to poor documentation by the Node-RED team, but I got there in the end 😁 |

can you share your configuration ? |

Yes would be nice to know how to set this up in NodeRed directly without having the need for HA. |

great job. can you share your flow? |

It's a great job, could you share it or public the flow? If that I would like to try to add mqtt to it. |

Wow this looks great! I'm also thinking of using Node-RED in order to implement the dashboard for my charger. Could you share the Node-RED flow? Thanks! |

This is a pretty old thread so my Dashboard looks very different now...
I stopped using OCPP a long time ago and have been using MQTT to control my Wallbox Pulsar Plus for about 3 months now. I've made a version of the Flow with all personal data removed, so if you'd like a copy, please send me a PM. |

PM ;) I was looking for that however i found: You can't send a direct private message to another GitHub user. Alternative ways to communicate is through their open source projects. If they have one, you could open an issue and ask a question related to that project. Hence i try it this way could you consider this a PM :) |

@sincze - OK, I'll consider it a PM 🙂 Meanwhile, please email me at... grant.keymer [at] gmail.com Replace [at] with the magic symbol 😉 |

@rsteininger where can I find the missing nodes? There may be an easy way, but I'm not seeing it.3 |

Hello again all,
Over the past few days I've been working away on a Dashboard implementation for my Wallbox Pulsar Plus charger. After trying to do it with HA automations, I realised how limited they are in their functionality so I've switched to Node-RED. Below is my first attempt. Interested to see what you think.
UPDATE - Now with current control slider and timer functions added.
