Missing data in response ? #39

Open garethmo opened 3 years ago

garethmo commented 3 years ago

Hi Guys,

I recently got a Kodac 5kw which I believe is the VMiii.., I hooked up my Pi this weekend and got the inverter talking to this awesome software.

I seem to have a issue some missing data as you can see from the below payload, i have 3 fields that are not returning any data data

"PV_in_watts":0.0, "PV_in_watthour":0.0000, "SCC_voltage":0.0000,

I have looked at the current issues list and cant see any thing on this, I have also noticed that a few of the examples that have been given from other people these fields are blank.

I've had a look in watchpower and the values are pulling though to the Bluetooth app so they def there, which leads me to think it may be a code issue. any hints to point me in the right direction would be great. in the interim ill dig some more

main CPU version is 41.16

Payload returned

I found this page below where he experiences the same problem and puts it down to the connection, thoughts ??

https://powerforum.co.za/topic/4969-my-diy-home-automation/page/2/

"The only problem is payloads on low speed USB need to be broken up into 8 bytes chunks so currently this is limited to 5 character commands ( 5chars +2 CRC +1 CR = 8bytes )

So commands like POP00 work 100% but ones like PBFTxx.x ( float voltage ) are hit and miss.

This problem doesnt exist if you're using a normal RS232 serial port but not much actually have these anymore."

I have exactly this same issue. Would also love to have any inputs as to how we can get this fixed to work with the raspberry pi.

Same here!

AlexPoliteRudenko commented 1 year ago

Same problem for me. Axpert VM IV 5600. @garethmo I used forked repo from this repo https://github.com/catalinbordan/docker-voltronic-homeassistant that solves problem with 8 bytes and still do not receive values for these fields. I assume, the problem could be with missing value for SCC_voltage as toher values are calculated basing on it. Does anyone get it work for Axpert 5,6 kwt inverter?

Yip looks like the same, I managed to just do my calculations in the front end, so I'm not too worried about missing that watt value

AlexPoliteRudenko commented 1 year ago

@garethmo please, can you share how you managed to do this. I'm totally new to ha. What values do you use for calculation?

If you go to devices and settings and create a helper. Just multipy the Volts and amps to give you watts ;)

AlexPoliteRudenko commented 1 year ago

@garethmo thanks, I get it. Seems pretty easy. One problem - my inverter stops responding ((( Even restart did not help/ Have you faced such issue?

garethmo commented 1 year ago

I havent, but just check your mqtt is running
