Esperyd´s Raspberry PI project
1. Google grafana as example
2. If you used my default image it will expand automatically. If you fiddled around you most likely screwed it up or as i said what sd card did you use? Ebay one??

thanks again Daromer.
for some reasons my filesystem did not expanded automatically.
SD quality is high (samsung) but my linux knowledge is very low.
Followed your link and now my disk got 64GB space.
thanks

Hi All, I've been using solar-sis as a reporting/graphing tool for my PCM60x but I was wondering how you can go about changing settings remotely on the device as well. For example- say if I wanted to change the max charging from 40 amps to 45 amps, can anyone describe how I could make that change? There doesnt seem to be much in the docs and I can't seem to make any sense of the Node-JS scripts.

I finally got my raspberry pi 3 in from China. I wanted to get your OS installed and play with it before I get my system up and running.

@daromer

I am having trouble downloading your Pi iso from you website. Both links are doing the same thing.

Here is the error it is giving me. Do you know why?

I have installed a new webbserver. Havent moved the ISO.

Will fix later today

would it be possible to read this data to activate  relays that only enables heaters to run when solar input is higher than loads / max export limits are reached and batteries are 100% charged ? 


I have a few of these in parallel 

http://voltronicpower.com/en-US/Product/...8a1Z8ptNxk

how can I go about reading multiple units ? and I am assuming if I use the serial connection USB connection to the laptop will still work ?

I see batrium support , would you be able to add in diybms support as well ?

my original idea was to use batteryless inverters for running the heaters but that plan back fired as single units could not handle the heater loads  so gone to hybrid inverters

If they are in parelell internally you read the data from 1 only. The protocol doing that is uploaded already. Or if they arent tied in parallel with the board you just insert one serial adapter in each.

I am scrapping this Image in short. I have built a totally new setup that relies on container based structure (ALOT easier to install and maintain). Yes Im working on the DIY bms part as we speak and it will be fully integrated into this setup with code in containter and flows in node-red Wink

Takes some time. It cost to get the gear but also the time spent is costly so i hope to get there soon.

I have also rebuilt the solar-sis into dongles that runs on wireless that connects directly to the inverters!!! Makes it more stable but i have bummer in the code that i need to solve. Keeping the price down generally creates more work. Stay tuned for this!!

thank you for the fast reply
I figured the ISO was dropped as v8 was 4 years old

I was wanting to be able to monitor each inverter individually and planing on still using solarpower program
as I am wanting to keep track of the solar panel strings have have ~minute logging
what I am unsure is how I should go about connecting so I can keep solarpower program connected via usb and make use of the unused serial connection
how many serial connections can be sent directly to a raspberry pi ? or is going serial to usb/wifi the better option

I will look more into solar-sis soon 20 pages to still catch up on here Big Grin

You cant have both running at same time. They will crash each others requests. You could write your own software that only listens on incoming data based on what Solarpower requests but thats it.

You can have as many connected to a PI as you want but beware of that most serial adaptors are very unreliable long term especially connected to the inverters in this case. I know this because i run 4 of them and they tend to break every now and then. Thats also why i have opted to go for an wireless system based on MQTT instead.

Current setup is based on this code https://github.com/daromer2/InverterOfThings that i of course forked since i was lazy. But i have big problems with what i call a bug where the ESP ends up in a loop after crash and dont reconnect to the wireless again. Im running the software serial right now and its notorious to be difficult when using wifi at same time but if that crashes i still think it should reconnect but it doesnt.

So if someone with actual mad skills there wanna help feel free to reach out. Backup plan is to go ESP32 and have dual hardware uarts or use the built in HW uart on the esp8266 but that renders current debugging useless unless i use software for that...

It is working though (I havent pushed latest update) with PCM60x/PIP4048/MPI series protocol.

hmm I am trying to keep wifi as low as I can ,
the networks quite crowded here I really need to upgrade to 802.11ax but MikroTik still have not released anything , almost 200 devices ... IOT just takes over .. mobile is barely usable and printing takes for ever 
I already split the network in halve , looks like I will have to keep dividing up my devices onto more networks 


I have been using these for running my projects 5v lately , shame no 12v / 24v option 

https://www.ebay.com.au/itm/DC-DC-36V-48...2634295401

ESP-07 or ESP-13 module with breakout adapter board ($3.00)
"wouldn't ESP8266 be more stable not that much more $ ?"
MAX3232 module ($0.50) - it's just a max3232 with 5 capacitors on a tiny little board
https://www.aliexpress.com/item/4000055222836.html
AMS1117-3.3V ($1.00) - Or any 3.3V regulator
USB-TTL serial module ($1.50) - Make sure it has RTS and DTR outputs
"this seems too cheap how to find something known to be reliable ? "


found your video using sonoff to control heaters looks like exactly what I am after so ordered a dozen r1 basics
I will just have to but a router in the aquaponics area
flashing Tasmota on their should not be a issue
I think it can be also modified to work with ds18b20 ?

shame I can not use both Solarpower / solar-sis , but dumping excess power into useful things is more important
plus grafana has better charts

what power meters am I needing to do the external monitoring ?
the ones I have found in Australia are hell expensive
