Monitoring & control software, what are you using and why?

Post by rthorntn »

Hi,

Apologies if I missed a thread on this, I did go through all the Non-EV posts and didn't see anything.

A week ago I had my SBU system installed, I purchased ICC but now I'm thinking that I might replace it, why you ask, well:

- It's pretty huge, running a full Linux graphical environment
- It crashed after running for only 4 days
- It's clunky
- It's buggy
- It's closed source

I'm a Linux CLI guy and I found https://github.com/jblance/mpp-solar, it looks like it might be what I want, I think my main requirements are historical logging of my data and MQTT so I can integrate it into Home Assistant to switch things on/off.

What are you using, why you using it, what do you think of it?

Thanks.
Richard

Hi,

I use Watchpower. It's free. Does what I want, monitor & change settings. Bit slow when retrieving past data, and date/time column has to be resized every f@#king time, but it's free. Did I already mention that?

I use watchpower but wanted a low power and low complexity remote system to monitor and control
the inverters so a smart control screen. Its been a bit slow and things changed along the way but
I have now in a testing stage a 7 inch Nextion touch screen working via a atmel 1284 micro
that shows all that watchpower shows and more , with multiple screens that I can also change
settings with I also have a sd card with the avr which will be used to log to. It is at present
connected directly to one of my inverters by a 40 meter long rs232 cable link but
with the use of HLK RM04 modules can be anywhere a tcpip link can be used.
Note I have PIs but running a full operating system with all the possibilities it has to go wrong
simple code of 20k or so seems more sensible.

Thanks @paulvk, I would love this, will you share the code?

I think I want MQTT, to get some key values from the inverter into home automation (PV/load/grid watts and battery voltage) so I can turn stuff on/off under different scenarios...I definitely need to switch my panels over to another inverter when my battery is full, my load watts are low and my solar watts are high. EmonCMS fed from this data would be nice also.

Arduino's can do MQTT and can have ethernet, could your system write some values to the serial console that could be read by another micro running TCP/IP and MQTT, I'm thinking of doing that to keep the "control" Arduino simple and reliable...

Already been posting code.
MQTT I think could be added but would have to add a wiznet W5100 board
and combine another members code for MQTT Note I write with Bascom
attached is the Nextion project if you download and install the Nextion editor
you can load the project , run debug and see the Nextion lcd working
also now that the Nextion can now do CRC it is possible to write the code
just on it to make a remote terminal but it requires code to parse the
rs232 buffer to be written as it normally just accepts standard commands.
Since I also will add other functions to the avr , battery banks current , temperature ,
auxiliary load current ,battery temps , environment temp I will stay with the mega 1284
as I already have the code written just have to add it

Note while writing this I am watching the Status2 screen on the Nextion showing my 2 inverters.
Regards Paul

Yes but the HLK RM04 is a router , wifi access point and two rs232 to tcpip and I have a few of them.

@rthorntn Sorry for bringing this topic back and i'm in the same boat as you with ICC and adding to your list is the super bad customer support which wasn't the case in the early days of ICC.

anyways, have you checked this project? I will be trying it soon.

I believe that ICC has split (again?), possibly due to support issues, and this fork seems to have far better support: https://centurionsolar.co.za/ . I don't have any association with them, and have never used ICC.

Thanks @coulomb, exactly, ICC has split, as far as I can tell it split a while back and centuriansolar is now an old version, maybe they don't have the source code. I guess it would come down to whether you can "get away with" the older version.

Manie mentioned he has the next version of ICC in testing, who knows if it will be version 3 or even called ICC, he hinted that it was a complete rewrite. I won't be buying anything else from Manie.

@PapaDocta, at this point in time I have paid for ICC and have it deployed, I won't be contacting Manie again as there is just no point, I had terrible instability with ICC, it wouldn't stay up for much more than a day, Manie mentioned a customer of his had issues with interference, I swapped the USB cable for a shorter, thicker cable with a transparent sheath that you could see shielding through and ICC has been running a lot better.

Who knows if I will stay with ICC.

Hi,
I am exploring this freeware solution from solaranzeige.de. Unfortunately this site is in german.
The package support a bunch of different inverters including PIPs, can handle up to 6 different sources, has MQTT, influxDB, Pushover, Grafana and homematic.
Support Wallboxes. Free download requires registration which is free of course.
I have no connection to them. I have still problems to get it running but there are several installations which you can access here for demo:
