"Hacking" my Victron MPPT to add ONE MISSING Function!

[@premkumar.g6510]

Really its working perfectly yesterday i implemented the same ,i can access all the functions properly i really appreciate your efforts...

[@KPeyanski]

Glad to hear that. Enjoy!

[@mariousai]

ohhh I love this! I'll try as soon as possible. at the moment I just integrated my Victron Smart Shunt by bluetooth, using BatMon

[@KPeyanski]

This is working perfectly so far. You have my two hands recommendation!

[@andabraha]

many thanks for this tutorial, I just set this up with my ioBroker (using esphome adapter). it saves me from using a raspberry pi in my garden house

[@STRANAIF]

Note that for the 75 volt model, the VE.Direct port is upside down. The pins from left to right then become 4 3 2 1 or 5V TX RX GND

[@KPeyanski]

Thanks for that info :)

[@richardmrozinsky3323]

Thanks for the tutorial! I had to change the UART id, but other than that all is working well. I'd like to set this up with the BMV-712. It would appear I need to add the various BMV-712 sensors into the yaml file. I'm not sure of the details yet, but if anyone else has instructions on how to do this it would be appreciated. Thanks again.

[@KPeyanski]

Glad it helped! For the BMV I can suggest to ask the author of the code in GitHub ;)

[@skm7812]

Did you find out how to do it with BMV-712? Thx.

[@fibranijevidra]

It would be cool to show how to intergate it to the HA energy dashboard.

[@FCTruter]

Agreed, great idea for a follow up video

[@KPeyanski]

Yes, I have to play with it first :)

[@uwe.herting.37431]

A Zigbee plug - or in this case a Wifi plug - which measures power would be the easiest for the 230V consumption. For charging some input might be used. So there is a in/out from the battery which shows up in the HA energy dashboard.

[@MrRoboto2338]

Shouldn't this also work with the Victron Blue solar version, which is only missing Bluetooth capability?

[@rolandkowalke]

Hi Kiril - I built the tool with the D1 mini pro and flashed it with your source code. Pin D7 connected to pin 3 and GND to PIN 1 of the MPPT. But my log just says: [W][victron:093]: Last transmission too long ago Can you tell me what's wrong?

[@jorgjungheinrich8572]

Same problem here. 😞

[@mr2web]

Same here

[@Francois_Dupont]

same for me with a ESP32 board. somebody ever found a fix?

[@Wim-ib6qn]

same here since a few weeks. it worked okay for a couple of months

[@staniprokaravanytomasloren6495]

hi, same thing too, anyone have a solution please?

[@robertwhite2171]

I have the ESP32 S3 mini board working if anyone needs the code. Also i was thinking maybe add a BME680 to monitor the temp and humidity of my enclosure on the wall.

[@paulsharp1712]

Hello does D1 communicate the data via mini usb or wifi network? Also can you connect multiple Victron devices? I have BMV-720 and 2x MPPT

[@NtotheO91]

Is there a specific reason why you choose the esphome over Modbus TCP for reading and writing data which Victron provides OOTB?

[@KPeyanski]

I don’t know how to make such an integration yet. Can you please share some links to some working solutions

[@thebobcotton]

The output of the solar charge controllers are ascii over serial only. You need a Venus on pi or a Cerbo

[@DincaSilviu61]

Hello. I’m from Romania and I have a home assistant system for monitoring the devices in the house. the photovoltaic system consisting of 4 mppt epever tracer 4210 and rj45 wi-fi modules. how could I integrate those mppts in ha? they are connected to the internal network and I have their ip. they work with epever pair cloud. I greet you.

[@DivinaFarms_James]

Did you add a voltage divider or logic level converter between the ESP and the Victron device? Or was it measuring 3v3 between Tx & Ground on your solar charger?

[@KPeyanski]

No, I'm not using a voltage divider

[@DivinaFarms_James]

@@KPeyanski All good. I ended up using esphome-victron_ble on an ESP32. So far it seems to be working.

[@Francois_Dupont]

in the picture you show connecting the WeMos to a computer using USB. is is possible to then run the WeMos board stand-alone after it is flashed? for example my victron is very far away from my HomeAssistant server.

[@KPeyanski]

yes, you can leave it wherever you want as long as it have a wifi coverage on the place you wanted to be

[@kconatymd]

will this work with the Multiplus Inverter/charger?

[@jackofmosttrades.masterofsome]

As usual a fantastic tutorial. Well done! This is the first time I have used ESPhome. I have a boat and just installed a victron charger on board. So this is perfect for me. However, my D1 mini will not connect to the wifi.... I had a spare D1 mini, so I tested it on my house installation of home assistant and that one wouldnt connect to wifi either (completely different router, Rpi etc)... I googled for solutions, tried them all and still no luck....... :( Any ideas?

[@KPeyanski]

What the ESPHome logs are saying?

[@jackofmosttrades.masterofsome]

@@KPeyanski I found this issue. The old incorrect wifi password trick! I changed it in the secrets and it still didnt work, which is where my frustration began and when I messaged you. It turns out that if you change the secrets info, you have to reflash esp. Or at least that is what worked in my case. I now have remote access to my battery charger on my boat! I used a different victron yaml to suit my model of charger, but it worked perfectly in the end. Thanks for the idea! :)

[@emphantom9122]

Hello. What other board can I use? For example esp32 WiFi.

[@KPeyanski]

In theory any esp32 or esp8266 board should do!

[@andabraha]

Do you know what I can do with ve bus devices (e.g batteryprotect from victron). This device doesn't have ve direct interfaces

[@Shawn-ts4jw]

batteryprotect does not have ve bus

[@andabraha]

@@Shawn-ts4jwyes Thank you, i noticed that too Unfortunately, I tried to extend the Bluetooth signal with bluetooth proxy over esphome without success

[@kpredkiewicz]

Out of curiosity - does this work wireless, or the data goes trough cable?

[@Francois_Dupont]

wireless thru WiFi

[@shaynewarren]

Is it possible to add another victron device to the same D1 mini?

[@KPeyanski]

I don't know maybe you have to try and see

[@Baje36]

Can i use ESP32 instead of 8266?. Great videos btw!

[@KPeyanski]

Of course, you can use both ESP32 & ESP8266. Also I'm so glad that you like my videos 😎

[@Baje36]

@@KPeyanski Finally got back to this. You have the wires labelled wrong in your video. Pins 1,3 When it should be 2,4. Great video otherwise! Thanks!

[@uwe.herting.37431]

@@Baje36 In the git repository pin 1/3 are mentioned, too. From where did you get it that it is rather pin 2/4 and which Victron device are you using? In the PDF about the MPPT chargers by Victron there is a jumper between pin 2/3 (the two centre pins) to be seen. Do you know the purpose of the jumper by chance? Thanks in advance!

[@Baje36]

@@uwe.herting.37431 No i dont sorry, But im using a Victron 75/15 Controller.

[@Baje36]

Update - Been a good few weeks and working without hitch so far.

[@fedemejuto]

My victron mppt has no bluetooth, its needed for the process?

[@kecke2937]

No I dont think so

[@holgerwinkelmann6219]

Does it also work with VE_Bus ?

[@KPeyanski]

No, as far as I know!

[@subthousandoaks]

Ty!!

[@KPeyanski]

thank you too...

[@sureaa]

Can I use Arduino IDE?

[@KPeyanski]

Probably you can, but not with this code and project

[@SayWhaaaaaaaaaaaaaaaaaaaaaaat]

YOU SHOULD STOP USING OLD CHIPS AND USE ESP32

[@LoganFan]

Hi my Friend. Good instructions, but its not working for me! Always in Log: - [15:10:00][W][victron:093]: Last transmission too long ago - No Data is coming!!! ESP is online, Script is like yours and cables are OK! Does anyone have an idea! THX all Its A Victron 75/15 Update! Everything works perfectly! I checked everything again and discovered that there was a short circuit on the prototype shield that my ESP is plugged into.

[@Wim-ib6qn]

I'm having the same issue. What is that prototype shield thingy? I have a short cable with a JST connector soldered to my D1,
