Hz reading in the Inverter monitoring flow needs to be divided by 100, is reading @ 5000

I updated my one 🙂

Yeah, I also changed mine and committed it to github about a week ago

I don't seem to be getting the PV1 & PV2 amps reflecting in my MQTT data, is yours working?

In Node Red change the device class on the PV1_Amps from Amps to current

 

Awesome, working thanks

I definitely owe you guys a drink, you going to come to a meet up?

Based in CPT and heading to Kazakhstan next week. Would've been nice though 

Likewise, I'm Centurion based but heading out to Serbia this weekend

WhatApp integration added to monitor the grid voltage, send a WhatApp message if the grid goes down and when it comes back on

Is this on the HA NR instance? I've been doing this with Telegram bots for years from all kinds of platforms (not only NR) and it works well, but I found that the HA Android App notification from NR is the most reliable.

No on the Inverter instance.  I'm also using the HA notifications, thought I might test the Whatsapp Bot for those without HA.

Just wanted to drop a quick note of thanks for the info from this thread on getting the monitoring setup for this class of inverters. I have a Sol-Ark 12k (american cousin to the SunSynk/DEYE/etc) and was able to make the connection. I am embarrassed to say that the biggest issue which wasted a toon of time was trying to get my RPI 4 setup to recognize the USB-RS485 dongle to work so for now I have Node-Red running off an old laptop for now until I can get a different USB-RS485 adapter. 

So far the Node-Red Flows that @Bloubul7 provided of the box! Many thanks Bloubul7!  The modbus registers appear to be identical. I am still early in the process of reviewing the data and getting it into Influx but will post an update on some of the hurdles I had to go through. Thanks!

Could you upload the flow so jacauc can add it to the repository?

Hi all.

I have so many questions;

I have a 5kw Deye inverter (Same as the Sunsynk) The Main board is SUN-5k-SG02LP1-CON-V1.4, I am trying to setup a raspberry pi to monitor the inverter. I can not find any article giving all the steps for this setup. I also do not know how all the different applications, Grafana, InfluxDB, Batruim, Node-Red, MQTT integrate with one another.
I have in the meantime tried to get any serial data from the RS485/ CAN ports via the RJ45 connections, I have reached out to one of the Deye support staff in China, and according to him, the RJ45 RS485/CAN ports are only for BMS connections, and that the RS232/Wifi port has to be used for Raspberry pi connections. I have purchased a RS232-RS485 converter, and connected it up with The "Cheap" USB to RS485 converter from Micro Robotics. I also Purchased a RS485 CAN HAT from them.

After I have installed node red, I have tried to get any data from the inverter, but nothing. The way I have done this is by selecting a serial input (/dev/ttyAMA0 or /dev/ttyUSB0) but I get nothing. I even thought that there might be something wrong with the PI, so I have tried it on a PI zero W, PI3 and PI3B+. Same results. I also tried to use the RJ45 connection by connecting pin 1 to A and pin2 to B, (and tried 7 to B and 8 to A).

Can some one please direct me to a step by step procedure to get this working, as I am "moedeloos"

Hi Riaan,

Modbus works via polling. In other words, by connecting to the port, you won't just start receiving the data. You need to send a polling command to the Modbus port (done via Node Red in the examples in this thread), including a register number, and the Modbus port will respond with that corresponding value. The flows in this thread use the Modbus register addresses as supplied by SunSynk, but I'm not sure if they will be the saem addresses for Deye. Perhaps you can reach out to the person you spoke to at Deye and request the Modbus address document from them, specific to your device? From there we can help you modify the Node Red flows to work with your device.

No step by step guide but there is a lot of info on the forum. 

 

You will need a CANBUS-USB converter to plug into the Canbus port on the inverter.

The DEYE is pretty much the same as the Sunsynk as far as comms are concerned.

 

More info on this thread.  

 

jacauc keeps a repository of the latest flows.

I am a solar noob and only had my SunSynk with battery and PV array installed last week with the SolarMan app for me to monitor but the app really is VERY basic and pretty disappointing. Although I'm very IT literate I am no programmer so the flows on the Pi would be a real challenge for me - not to mention I don't have the kind of time needed to dedicate to this.

Is there anyone who has considered selling a package including the Pi, setup, visual dashboard, WhatsApp notifications etc. I'd be happy to pay someone else for their time and expertise if it gives me the kind of info (and control) that seems to be available.

This is probably what you are looking for then: https://solar-assistant.io/explore/sunsynk#hero

Thank you JuanH, this looks like it will give me a much better idea of what is actually going on. Do you know if there are any plans to build in more intelligence like being able to control pool motors, geysers, etc. when there is excess PV? Ultimately that's where I'd like to get to but this is a good start.

From what I understood from the developers of Solar Assistant, they plan to integrate with Home Assistant. Using HA, you'd be able to set up that sort of automations. 

I'm currently automating a lot of my home based on available PV output, but I'm using the DIY solution in this thread to integrage with Home Assistant.

I assume that Solar Assistant are not based in South Africa? I tried to look on their site but they don't say (I have dropped them an email). 

An integration with HA would be a very good solution for those of us who are less technical, let's hope. I'll hopefully hear back from them shortly and then I'll make a call on buying one for the dashboards.
