You are on a good track. If your inverter is able to answer to QPIGS requests the pipsolar component should work for you. Just assemble all parts and give it a try. Please report your progress here. |

im about to start. grid_rating_voltage: can I change the id:, and the name: for something that makes more sense to me? does the name has to have the undescore ( _ ) or can i change them for spaces? sorry for the silly questions I dont know how to code and i dont know yaml. how is that you just use name and not id in your code? grid_voltage: 73 de KP4MI |

Hi! Good job!! Can you say me How you have integrated energy battery charge/discharge information? Pipsolar inverter don't have this information. There are only charge/discharge currente. Does You have calculate power and energy from (voltage * amper)? |

same problem but i'm on 8266 i don't understand how to make the pipsolar show up on the energy distribution flow card, shelly utility appears just fine. EDIT: I am too stupid to be making this kid of stuff. All of this should be integrated or explicit on pipsolar.

Hi Sebastian,
a. CSO - solar energy will charge battery as first priority. Utility will charge battery only when solar energy is not available. b. CUt - Utility charge battery as first priority. Solar will charge battery only when utility power is not available. c. SNU - Solar energy and utility will charge battery at the same time. d. OSO - Solar energy will be the only charger source no matter utility is available or not. thanks |

I'm using 4 PV strings in parallel so just one string is going to the inverter and I only have one inverter. here are some logs, let me know if the QPIGS response is there, if not please let me know how to add them: the SBU feature is working, I can select the Output Source Priority: `switch:
I will like to add the Charger Source Priority. the Output Source Priority: (option1 in my inverter menu) will allow me to configure the load power source priority, basically which source will be used as output to power my house the Charger Source Priority: (option16 in my inverter menu) will allow me to configure the the priority of charge source , basically which source will be used as charger for my battery bank. attached is the inverter manual: |

I tried the new code and woks as expected it chcles between all 3 modes solar only, utility only and sbu, thanks so much now when i switch to utility only (even if I do it manually) and the back to solar or sbu my inverter output stays in utility ( even if I go to the menu and verify that the mode has changed) I think thats a limitation of the inverter I did all these test with my battery at 100% soc and plenty of sun. in another note I have a crazy idea and dont know if it possible: thanks for all your support |

You are talking about the SUB-D 9pol jack of your converter module, right? Your inverter provides only one serial interface via RJ45? |

my inverter has both ports sub d9 and rj45 the both are serial ports but dont know if is 1 port 2 form factors or 2 separate serial ports |

Hmm.. interesting. I wasn't aware of a second connector. Are you sure the Watchpower Android App is able to handle a serial connection via WiFi? If I read this page it looks like some cloud is involved and the Dongle does some conversion here: https://www.mppsolar.com/v3/portfolio/watchpower-wifi-new/ If the Android app is able to connect to a serial over wifi stream it's pretty easy to add a serial-to-network streamserver to the YAML. I did the same already for a ZigBee Gateway (the ZigBee Modem is attached to a serial port of an ESP): https://github.com/syssi/esphome-zb-gw03/blob/main/packages/core.yaml |

yea you are correct dongle does some conversion and goes to the cloud. have you seen that behavior, that the inverter output will still utility even if solar only or sbu are selected?
isntead of this
like i mentioned that happends with or without the esp32 module even if i change it using the menu |

I know that if you have the switch off, AC will go into bypass mode. You can change setting bypass enable/disable modes on option 23 on mine. Look for byE is probably on. I'm using a smart switch on my AC input to remotely turn it on if I notice battery Ah are getting less than about 15%. Eventually I want to automate changing option 16 after reading my shunt Ah left and if needed, enable the bypass. I don't want the AC charging batteries too much if it gets low, only charge enough to make it to morning. But then I also run down to shut the switch off because even in eco mode, it drains the battery. That's another thing I want to do, such as put a relay to the inverter switch. But I'm not confident if esp32 keeps the latch state. hope this helps you. |

hello Sebastian, I think will be something like this but dont know how to implement it I think that the command for charger source priority is PCP is there a way to make the a switch ( preferred method ) or to use it in automations. |

hello
this is my solution:
substitutions:
devicename: "SmartShunt"
accuracy: "3"
- platform: template
name: " ${devicename} charge "
filters:
- multiply: 0.001
unit_of_measurement: kWh
device_class: energy
state_class: total_increasing
accuracy_decimals: ${accuracy}
lambda: |-
float i = 264 + id(consumed_amp_hours).state;
float e = id(bv).state;
float w = 0.0;
if (i > 0) {
w = i * e;
}
return {w};
- platform: template
name: " ${devicename} discharge "
filters:
- multiply: 0.001
unit_of_measurement: kWh
device_class: energy
state_class: total_increasing
accuracy_decimals: ${accuracy}
lambda: |-
float i = id(consumed_amp_hours).state;
float e = id(bv).state;
float w = 0.0;
if (i < 0) {
w = i * e;
}
return {w * -1};
change the 264 for the amount of Ah of your batteries.
this will create 2 new sensors:
SmartShunt charge and SmartShunt discharge , use them in your Configure
battery system screen

What pipsolar value is your " id(bv).state " and id(consumed_amp_hours).state ? |

no. Power Discharging Battery is: if youbcopied the piece of code that I posted, you will have 2 new sensors, in this case they will be SmartShunt charge and SmartShunt discharge.

no I use victron smartshunt, by KinDR007 for my battery sensors. I just use pipsolar to monitor my mppsolar inverter. here is my code: in the 1- you will need to replace the number 264 in the following line: 2- look at the 2
3- I also removed everything related with Wi-Fi monitoring in my code. 4- one last thing in the I hope this helps, just let us know. |

hello Sebastian, I have a Victron smart shunt code by KinDR007 and SoC is different between the 2 integrations

I don't know. It's calculated by the BMS firmware. I assume it's a prediction based on the different cell voltages, the battery capacity and the delivered energy since the last full charge. |

I played with the low voltage cut off in hopes of giving a 10% buffer to actual low voltage and the percentages of SoC changed. I was trying to also see what the top off voltage was for fully charging the batteries because I didn't have a stand alone charger and I'm running 24V with two in series. What I could suggest is throwing away this value entirely, making a parameter in the yaml file that lets you define the battery type and then show the percentage based on the battery voltage state tables to make more sense on Pipsolar than what the output is from the mpp variable. I use a Junctek KJ140f shunt and that has been spot on, but I still need to pull its RS485 signal into something usable like pipsolar's page. |

hi Sebastian,
I put the bms project in pause.
now i will like to integrate my mppsolar lv5048 to my HA. I see that there is an esphome integration (PipSolar PV Inverter) and also your repository esphome-pipsolar.
do you know if any of them works with my inverter?
i have a step down and a rs232 to ttl converter already an of course an esp32
this is my ttl converter. according to the sapecs should be 3.3 tolerant.
