"fixed32 dcTwoIn = 70;" gives an error: Wire format is invalid: RangeError: index out of range: 1261 + 10 > 1261

110-116	70	fixed32	
As int: 0
As float: 0

"fixed32 dcOneIn = 361;" seems to work fine

373-379	361	fixed32	
As int: 0
As float: 0

They both look the same "fixed32" but for some reason, it can't decode it

"fixed32 battIn = 3;" gives an error: Wire format is invalid: Error: invalid wire type 4 at offset 548

2-7	3	fixed32	
As int: 0
As float: 0

"fixed32 battOut = 4;" seems to work fine. However, interestingly, it wasn't working when I started this post, but now it's working fine (I hope it stays that way)........... having said that.. sometimes it works and then it stops for a few mins then starts working again: Wire format is invalid: RangeError: index out of range: 1257 + 10 > 1257

7-12	4	fixed32

I connected a 12v power supply and was able to decode dc_in_02 , 01 does not work, still checking.

    syntax = "proto3";
    
    message MessageFromJson {
    
        repeated subMessage_1SubMsg sub_message_1 = 1;
    
        message NestedsubMessage_1SubMsg {
    
            optional fixed32 battery_level = 262;
            optional int32 target = 8;
            optional fixed32 ac_power = 54;
            optional fixed32 ac_out = 368;
            //optional fixed32 dc_in_01 = 70;
            optional fixed32 dc_in_02 = 361;
    
        }
    
        message subMessage_1SubMsg {
    
            NestedsubMessage_1SubMsg Nestedsub_message_1 = 1;
    
        }
    }

@phoniclynx The root cause is that the message coming from ecoflow has some nesting in the protobuf structure that I have not been able to parse.

for example, dc_input 1 is located at position 70 as fixed 32, but on the next value of the array, position 70 has a string message, this causes it to fail decoding.

the other values do not have this problem and parse just fine.

fwiw, value 3 is combined dc input, 70 is dc_01 and 361 is dc_02.

Did you mean 70 is dc_02 and 361 is dc_01? That's what I worked out on mine.

I'm guessing you need to parse the protobuf file differently?

I've also noticed a small error in the way you've set up the sensors. Category and Last Reset should be blank: (According to this: HA Forum Link - but I could be wrong)
image

However, Last Reset should be filled out here: (If not, you are not able to use it in the energy pages)
image

I'm not too sure if the actual date means anything or if it needs to be calculated elsewhere for some reason. But it does stop the Energy pages from throwing up an error message.

The final step is to get that protobuf nesting solved; then, it should work quite nicely. Until we find a different error LOL
