Hey folks, In the past week or so I've noticed that Solarman keeps going offline for various lengths of time. Today has been particularly lengthy - since about 4am it's been offline. Is there anything that can be done to change to a different server or something? Its not my wifi connection but the servers that they connect to...

Hi Guys Been lurking for a while and installed an Esener 5.5k inverter which is pretty much a rebadged Axpert and Mecer unit from what I can tell. Coupled to that I have a Esener 5.1 Lithium battery. Both being Esener it was pretty much plug and play and so far even stage 6 has been n breeze and without solar panels yet. I did the install myself and so far my only issue is the Wifi dongle that must talk to the SmartESS "server". I connected the Wifi Plug Pro data logger to the inverter as per instructions. I can then connect to the data logger via my phones wifi. So far I have managed to : Create an SmartESS account Connect to the wifi datalogger …

For my Sunsynk5.5 Simple Local Monitoring and Graphing Solution I use a single RPi4 2gig + 1 terabyte external HDD + Official RPi4 Power-supply. The comms between my RPi4 and the Sunsynk 5.5 inverter is done using the Sunsynk BMS RS485 port wired to a standard (RS485 to RS232 Converter) and then to a standard (RS232 to USB converter). This comms setup gave me the most stable and fastest/reliable way to get the data from the Sunsynk. You can still use your Solarman or Sunsynk dongle at the same time. Credits Shout out again to @Bloubul7 who has an awesome post going about using nodered and Sunsynk That was the foundation for setting up my own dashboard runn…

Be warned, I am very new to this and may need a lot of hand holding... I'm busy building a home automation system using Openhab on a Raspberry Pi. One of the rules I want to incorporate is switching the pool pump on or off depending on the SOC and total load readings from the Goodwe. I can get these from the app when I'm on the home wifi so it should be possible for OH to ask for the information but I can't seem to find any information on how to do this. I found some guidance on pulling this from the SEMS portal but I'm concerned about delays. I want the pool pump to switch off as soon as total draw reaches 4kW or higher. Has anyone tried something like …

Hi everyone, I woke up this morning and found that one of the 2 inverter's data logger is blinking green while the other one is blinking blue. Please also note that nothing has been changed in terms of configurations. To find the root cause of the issues, I have done the following steps: Removed the logger from the mobile app (Shinephone) Reset the data logger but could not connect using the standard mode while noting that the first time it was installed I used the standard mode. Tried the hotspot mode after clicking on the "key" button with a short press and was able to connect to it but the light is still blinking green. I Tried also rese…

Hi folks, I was given a ShineWifi-F dongle by @Demo after his Growatt inverter was water damaged. There are a few threads about reprogramming the Shine-Wifi-F dongles (e.g. https://diysolarforum.com/threads/hacking-the-new-growatt-wifi-f-modules.43231/), but one of the constant problems is programming it, because of the RS-232 transceiver connected to the ESP07 modules RX and TX pins. Some folks desoldered the transceiver, others cut traces, etc. Some had success with particular USB-TTL adapters, but the CP2102 that was said to work there didn't work for me. Others had problems providing enough power. I approached it somewhat differently, starting with a USB-RS232 dongle,…

Hello everyone

Hi all, Thought I'd share my journey in creating an accurate water level measuring system for my Jojo tanks. I've finally managed to find a solution which is about 99.6% accurate. This equates to a water height difference of +-5mm between the actual height in the tank vs what the probe is reading. I'd call this a success 🙃 Some of the other ESP32 + sensor solutions which I've tried and given up on: Waterproof ultrasonic sensor - difficult to implement as the minimum distance between the sensor and the water level is +-20CM if I recall correctly. This meant that I would need to 3D print a cone to raise the ultrasonic sensor and cut a large hole in th…

I want to connect with Rasbery Pi to this inverter i have https://www.aliexpress.com/item/1005002328132162.html It works with provided WiFi Dongle and SmartESS application but Solar Assistant does see incorrectly the devices when connecting both usb and rs242 cables together or independently. when plugging in the inverter via USB it's showing up as a "Exar Corp. XR21V1410" serial device which is different from normal. This USB device is also not accepting connections.

Any suggestions on something that can give a reasonable daily chart/graph of geyser kwh usage? Efergy looked like they have with their "engage" but they seem to be dropping off here for anything available & overseas stock also looks like their about to close their doors. Ewelink + Tuya - I really thought there would be something better but doesn't appear so unless I'm not looking in the right place. IamMeter - seems expensive @3k for a single CT Feeding to Victron VRM looks like also a $ story & maybe a chart but no totals either. Any other suggestions to look at? Edit: Deeper look at the iammeter got me a bit keener on that one seen as the cloud…

Don't make the same mistake I did when buying your smart devices that you want to run on your own network away from the cloud. Make 100% sure that the devices you buy can be flashed with your own firmware or tasmotised BNETA devices which are being pushed all over SA at all the major retailers are NOT flashable, they are now using the new tuya proprietry chips which cannot be flashed with your own firmware or tasmotised. Ask your retailer if the devices you are interested in are using TUYA chips and if they are, walk away These companies want to force you onto their cloud systems so that they can sell your usage data to big tech and who knows else. If TU…

I have a technical question and I'm counting on some advice. I've already updated my new inverter Voltronic VM IV 3600 to the latest available versions 61.03+22.21 and I was hoping to be able to turn on the Eco mode - unfortunately the inverter draws 18W at rest and after switching on the converter without load it draws 75-80W just to maintain operation. Can i turn on the Eco mode in it?, or is there a firmware that will slow down the fans? I think it would be possible to reduce a good 10W by muting the fans. Maybe you have some other methods? I don't hide the fact that energy efficiency in offgrid is very important to me. I realized that I will probably ne…

Hi guys, Just wanted to present to you a new Windows' software tool that we prepared for monitoring of PIP/Axpert inverters and Pylontech batteries. It supports many compatible inverter models. It can work with parallel configurations as well. This was actually the main reason to write the software because a few months ago I upgraded my system from single to 3x inverters and the "pi" solution did not work correct anymore. The software can control switching between battery/grid mode based on Pylontech SOC, and also can control Pylontech max charge current based on the request coming from its BMS. The software can also upload data to emoncms server. Currentl…

Need some advice with Wifi app please. Deye 5kw inverter. I’m rather disappointed with the basic Solarman Smart App compared to what I’ve seen for Sunsync. Is Solarman smart app the only option?

A few days ago my Luxpower app on my phone and laptop stopped working. When i tried to log on it gave a message...Network may have trouble. I uninstalled the app on my phone and am trying to download it again but its not working. Any answers out there.

Gents, Don't worry. I don't even open the DB board's see-through cover, so I won't go fooling around with the electrical system in the house. My question is, Do you get a WiFi switch that can be installed on the Eskom supply on the house DB?

Hi I would highly appreciate it if someone could assist with getting view power running on Pi I have installed but have been away from linux for quit a while

I am interested in upgrading to the Luxpower SNA6000, is the app/remote access useful for configuring? Also, can it be configured so that it can work with the Smarthome or Tuya platform, or what is recommended? Example: automatically adjust charging profiles from solar based on weather forecast? Or turn non-essential loads onto mains supply instead when sun time is reduced by weather conditions?

Wow, I got ICC-Solar on Pi running yesterday. This is absolutely brilliant. Awesome piece of software. Is Manie no longer on these forums - havent seen his posts since about Jan 2018. Anyway thanks Manie. Just had to comment on it.

I've purchased a used Solarman Wifi Logger to use on a Sunsynk 8k. When I try to add the Logger to my Plant on the Solarman Smart App it says something like " Logger already in use on another plant. Please refrain from adding multiple times" Any idea of how I can get it to work ?

Hi everyone, my Luxpower SNA5000 inverter is working normally, but the Wi-Fi dongle keeps saying in the monitoring APK that this dongle number is existing. (It came with the inverter box and is brand new.) I did a factory reset by following some posts, and the local connection is done, but it failed to go online. Please help me again.

I've seen on some users on this forum that are owners of Sunsynk/Deye inverters who create their own monitoring hardware, like a Rasberry Pi or similar, using the modbus connection directly to the inverter, and accessing the data via local IP. They match the register info and can create their own dashboard and control centre using it. Similar to Solar Assistant, but with more control. Has anyone here sucessfully managed to do this and be willing to share how? Jay

Hi would like to find out how to to link my deye inverter to the deye clould app.

Hi all RPi fans with ICC, Is it possible to use the RPi to run the debian linus version of Watchpower on? If so, can one use the USB cable to communicate to the Inverter, or does one still need a USB to Serial converter, and then run both ICC & Watchpower at the same time? I would rather go this route then having a dedicated Windows machine to occasionally look at WatchPower. Your thoughts/suggestions

After the update on my raspberry pi from ICC software site update from Marnie, my Emoncms web and the local emoncms is no longer working. The web emoncms is no longer getting updates and the local emoncms is no longing updating have anybody a workaround to get them working again. thanks
