Barezzi: Cool, emoncms is a fantastic tool and recently I started playing with node-red on my pi3+ to automate some of my loads based on battery SOC. That said @essegis if setting all these up from scratch sounds daunting. You may go the faster route below: 1. Acquire a pi3+ or pi4 2. Get a minimum of 32GB SD card (preferably class10 upwards) 3. Head to IC software dot co dot za to download the trial version of the ICC and if you like it, you can pay for a licence key. The ICC software has a lot of stuff including emoncms already pre-installed and according to their documentation, it's compatible with victron and axpert inverters. 3 Likes 1 Share

I guess one would need to also invest in that switch that is so able to respond to command instructions right? ojeysky: |
Re: Solar Energy, A Complement To FTA by ojeysky(m): 1:45pm On Aug 27, 2020 |
ojesymsym: Yup, I got the sonoff basic at 5.5k each, it's cheaper if you are buying in bulk and each of them has 2.2kw capacity so you can put suitably sized multiple load on a switch. |

ojeysky: Thanks bro. In my search I saw some devices e.g. Sense. They had little clamp on meters where they get the current from and use that to do power and energy calculations. Looks like with you guys systems this is already settled with a BMV right? I don go store your reply sharply oo. Remote monitoring has become a must for me as e be like say I don too dey disturb madam to go check things. |
Re: Solar Energy, A Complement To FTA by ojeysky(m): 4:27pm On Aug 27, 2020 |
essegis: Yeah there is BMV in the mix of my set-up, that's where I get reliable SOC of my battery |

ojeysky: Thanks bro, tried responding yesterday but was banned for 24hrs. I thought as much too and when u mentioned it u Linda confirmed my fears. I took of the balancer and the battery has picked up, difference of .2v - .3v between the batteries which is quite acceptable. But am also thinking the balancer might be bad, bought it 3yrs ago when I had problems with my batteries then and it worked quite well till almost at the 3nd when I threw out the batteries. Now it seems to be doing the direct opposite. Has anyone experienced this before? ![]() ![]() |

NiyiOmoIyunade: True bros, IF all you want to do is see a bunch of data and like to dig into codes and commands when anything goes wrong as they often do. I was introduced to Home Assistant and Node Red by a gentleman (a super sys admin in my place of work) who was running his automation using python and emoncms. When he discovered Home Assistant and Node Red, he realized that they are better than hunting around Linux with commands. The obvious advantage with these tools is that, like myself, you don't need super coding skills. You actually don't need to code at all. You also have visual cues and representations of what you are doing and getting. When things go wrong, you can easily see what the problems are and resolve them. Actually, these platforms are built on python, Home Assistant, Node Red, Openhab etc. They are like GUI for python scripts and what you get out of them are limited by your creativity. Like I said, my Linux is very rudimentary, yet I'm able to use my Pi to interface through Bluetooth with my ANT BMS, all three of them, get their data, on continuous basis, and post them to Home Assistant for storage and display as you can see below. 1 Share

Good evening all, Pls can I have a review of GSR products from the house pls. Anyone that have used either the battery or inverter system. Want to recommend their battery and also want to get 2.2kVA for myself. Any info shared will be highly appreciated. Thank you in anticipation. |
Re: Solar Energy, A Complement To FTA by litaninja(m): 11:47pm On Aug 27, 2020 |
Late response here, but do you actually want to go via the internet? I'm guessing you're going through some form of public cloud? Personally, I don't like having a public cloud service open a tunnel the way most are wont to do. Flashing Tasmota & going via MQTT keeps it local, and if you do need external access, i'd recommend some form of vpn to be setup. Just keeps you in charge completly. ojeysky: 2 Likes |
Re: Solar Energy, A Complement To FTA by earthrealm(m): 12:02am On Aug 28, 2020 |
saint2ace: Wow, nice one. Whats the make of the balancer?...ha01 or ha02? Perhaps you touched both ends together inadvertantly @ojeysky, could you explain why balancer isnt needed for 2 battery in series |
Re: Solar Energy, A Complement To FTA by ojeysky(m): 12:26am On Aug 28, 2020 |
earthrealm: Since it's just 2 cells of 12v of same life history in series without multiple Ps or Ss(e.g 48v) involved I don't see the need for a balancer in such a scenario; both ends of the charger terminates on either sides of the 2 batteries in case of 24v so I don't see why there should be an unbalance in such a scenario if everything is fine with the 2 batteries. It's a matter of choice though but I don't see the advantage except that there may be a disadvantage in the case of a balancer that is failing. |
Re: Solar Energy, A Complement To FTA by ojeysky(m): 12:39am On Aug 28, 2020 |
litaninja: Not just any cloud, I needed to connect to my eWelink Account, it's same thing I would have done on my phone if I needed to configure the default sonoff basic. It's the same thing you and I are doing when we connect to our mail service through a client (e.g phone app) That said, I probably will flash tasmota in future but that will be to address situation where my internet connection is down. 2 Likes |
Re: Solar Energy, A Complement To FTA by saint2ace(m): 6:25am On Aug 28, 2020 |
earthrealm: I use the ha01 and about touching both ends together, I can't be sure to be honest, anything could have happened in the past 3yrs. So I guess @ojeysky is right, the balancer might be failing or has failed...... Trash in here it comes ![]() |
Re: Solar Energy, A Complement To FTA by litaninja(m): 7:40am On Aug 28, 2020 |
Heehee. Not quite same. With a mail client, you open a connection, fetch your mails and close same. For most devices control, a tunnel is open and same can be exploited to gain access to your internal network. And if the internet is down, well...even a VPN won't help. Lol ojeysky: |
Re: Solar Energy, A Complement To FTA by ojeysky(m): 10:04am On Aug 28, 2020 |
litaninja: You are right mail may not be the best example, a third-party social media app may be a better example, but I should note that it connects securely (https) through the api to the eWelink server, that's the situation that my eWelink app on my phone will be anyway. Ultimately it's not the best solution but it works for me until a time when I have enough motivation to flash tasmota ![]() 1 Like |

The HA02s tend to fail randomly and you only get to know when they have [nearly] killed your battery. Once we made these devices mainstream there was an influx of cheaper versions from questionable sources and everything went downhill from there. Also the ability to truly balance batteries was actually limited as the circuitry cut out too early. They may help a good battery bank in great condition, they certainly won't save a failing battery bank. My dissappointments made me work out a more reliable balancing method saint2ace: |

Boss, I am not bashing node red or HA o. I just said they were crutches for the newbies or DIYer who does not want to go to technical or into the backend of how things work. Some of us actually like to code and get into the backend ops of stuff and if I can in a script of no more than 50kb achieve thesame results as Node Red and other platforms why sweat it? I have basically emailed my custom scripts to clients, used Teamviewer to remote logon to their PCs, SSHed into the connected RaspBerry Pi, PSCPed files from PC to Pi and setup automated monitoring within 1 hour all easy peasy. It could end up a lot more complicated if I used generalist software. No need to install or setup node red or other elaborate stuff when all you are doing is reading output from a device and spitting it to database for processing - it is a minimalist approach that works well on a variety of platforms with zero hassle. Along the line also rediscovered my love for Linux and shells from my network admin days back in 2007 so a win win all around. The key is to use tools you are comfortable with and understand well to achieve your objectives. A higher goal is to gain extreme depth in the detailed inner workings of the devices you use/support. I am more inclined to the higher purpose as a techie person. I recently had to write an interfacer to talk directly to PylonTech batteries over RS 232 serial. Till now there are no publicly available ready made software to do it and PylonTech is very close mouthed with their battery admin software. There are benefits to using ready made tools where suitable but if you can code up a light weight better tool that thoroughly meets your specific needs, then amen and so be it!!! More learning and fun all around. adrusa: 4 Likes |

ojeysky: Actually, once you are connected to the internet, you are open to some risks. But, internet has become so important that the fear of intrusion shouldn't stop anyone from exploiting whatever it has to offer. One just need to practice commonsense security. Good passwords. Some firewalls, especially on the WAN side and avoid using your home network for storing anything critical. Though I try to protect my network, but I doubt if any intruder will find anything useful to other than switching on or off a few of my switches. Even Tasmota also has an internet interface through which you can do OTA updates. And not connecting to the internet will deny you the ability to remotely login and control your system. And that is a major icing on the cake for me. I can remotely start charging with NEPA if the sun is not good enough. I can check to make sure that my water has pumped. I can even shutdown the TV when my children are spending too much time with. The possibility is endless. 2 Likes |

Re: Solar Energy, A Complement To FTA by ojeysky(m): 2:46pm On Aug 28, 2020 |
adrusa: Absolutely Bro, thanks for talking about sonoff as that was what Ignited my curiosity. Now my freezer is permanently on and automatically turns off/on according to the status of my battery. Lots of possibilities with IOT. The reality is that if you want to enjoy automation with remote features one should not be scared of the internet, just be sure to isolate things as much as possible. |
Re: Solar Energy, A Complement To FTA by ceaser: 5:52pm On Aug 28, 2020 |
adrusa: Well, I like to use the web for controls too, but the problem of security is not something I wanna have to battle with. Even the security cams that I have installed only cover the premises, not inside the house as much as I would have loved to. That is why I resort to using switches over GSM network providers. I may not have the privilege of continuous monitoring like it is with raspberry pi mini computers connected to the internet and stuff but at least I get to throw a few switches with phone calls and DTMF tones, SMS communication/control and get replies for status monitoring. I think this is safer from hackers. |
Re: Solar Energy, A Complement To FTA by ojeysky(m): 6:55pm On Aug 28, 2020 |
ceaser: Security is sure a concern but there are ways to reduce that which is by isolating and putting your critical/sensitive tools behind access rules (firewall). For instance the IP cameras in the room could be denied access to the internet while they keep doing that important job of surveillance (though that also require getting a non internet dependent cams)
That's is also some form of network you know ![]() |
Re: Solar Energy, A Complement To FTA by adrusa: 7:16pm On Aug 28, 2020 |
ceaser: I have a few cameras inside my house. I like to be able to see round the house in the night or when not at home. I however avoided the rooms for obvious reasons. Again, I know it carries some risks, but then I'm not Bill Gates or Dangote or a big politician. I'm not entirely sure my risks are that high. Anyone who has the resources to break into my network to see me and my children watching TV is welcome. This not to say that I don't take security serious, I do. 1 Like |

tonididdy: open and visually confirm that the levels are ok. . and its not the indicator giving a false reading. 2ndly another possible cause is that your charge voltage is too low, this will make the battery sulphate. your absorb voltage should be 14.8v to 15v, while float should be 13.8v. i hope you have changed that your old CC, cos i remember your saying that the charge voltage settings are not editable. 3rdly, use a hydrometer and ensure the specific gravity of the electrolyte is ok..do this check when they are fully charged 1 Like |
