Latest Update needs https to work (dont verify the cert or safe it via a web browser). Also the Display does no longer work and the STATISTIC variables are all gone.
Hint: To get STATISTIC values you can use the API for meinsenec.de, https://documenter.getpostman.com/view/10329335/UVCB9ihW#17e2c6c6-fe5e-4ca9-bc2f-dca997adaf90
For a personal project I wanted to show the current status of a photovoltaic system made by Senec on a small display in the living room. Till then I used an old Android smartphone with a disabled screensaver, which showed the local webinterface.
To get to the webinterface in a browser you can use the following link, which will give you a website like shwon below.
https://SENEC_IP/
Another interesting link show you a representation of the display. So you don't have to check the appliance yourself.
https://SENEC_IP/Display.html
Edit: this is broken as of September 2023, the Display will stay empty
Finding the hidden API
To get this working I needed to know how the local webinterface gets its data. This was much easier than expected! Using the Developer Tools in Chrome, expecially the Network tab, I was able to see a POST-request which was made repeatedly.
Then I tried to mimic this request with Postman, which worked instantly for some parameters. After some testing I noticed, the content of the POST-Request is important! It determines the size of the response. To get all possible sections for the request you can POST the following.
Request Type:
POST https://YOUR_SENEC_IP/lala.cgi
Header:
No special headers required
Body:
{
"DEBUG": {}
}As a response you will get a list of all the possible sections you can include in your request. See SECTIONS below:
{
"DEBUG": {
"CHARGE_TARGET": "fl_00000000",
"DC_TARGET": "fl_00000000",
"DC_TARGET_PID_KD": "fl_3CA3D70A",

]
}
}The following is a sample request to get a lot of different data points. You mix and match the sections you want/need for your project. But remember, that the response will take more time the more sections you request.
Request Type:
POST https://YOUR_SENEC_IP/lala.cgi
Header:
No special headers required
Body:
{
"ENERGY": {},
"PV1": {},
"PM1OBJ1":{},
"STATISTIC": {},
"RTC": {},
"LICENSE": {},
"LOG": {},
"WIZARD": {},
"BMS": {},
"FACTORY": {},
"DISPLAY": {}
}You could also shorten the list of parameters you want to query. This will speed up the process a lot! e.g.:
Request Type:
POST http://YOUR_SENEC_IP/lala.cgi
Header:
No special headers required
Body:
{
"ENERGY": {
"GUI_BAT_DATA_POWER": "",
"GUI_BAT_DATA_FUEL_CHARGE": "",
"GUI_INVERTER_POWER": "",
"GUI_HOUSE_POW": "",
"GUI_GRID_POW": "",
"OFFPEAK_TARGET": "",
"STAT_HOURS_OF_OPERATION": ""
}
}The answer to this will look somethin like this:
{
"ENERGY": {
"GUI_BAT_DATA_POWER": "fl_C3BAD251",
"GUI_BAT_DATA_FUEL_CHARGE": "fl_42A2E5E4",
"GUI_INVERTER_POWER": "fl_80000000",
"GUI_HOUSE_POW": "fl_43B24272",
"GUI_GRID_POW": "fl_C04851EB",
"OFFPEAK_TARGET": "u8_64",
"STAT_HOURS_OF_OPERATION": "u3_0000183E"
}
}Next I will show you how to interpret these values und convert them on a Arduino based board!
Interpreting the parameters
The format of these values is always the same. It starts with two characters which represent the type of data transferred. For example fl_ means float and u8_ means uint8 which is a 8bit unsigned (one byte) integer array.
This definition is followed by the value represented in Hexadecimal, not Decimal. So you just have to convert hex to dec. An example:
"GUI_BAT_DATA_FUEL_CHARGE": "fl_42A2E5E4"
fl_ means this is a float value composed of 4 bytes.42A2E5E4 is the value written in hexadecimal, representing the 4 bytes of a float.
If you use an online converter like https://gregstoll.com/~gregstoll/floattohex/ you will get the following value: 81.449. This means the battery of the Senec photovoltaic appliance is currently charged to 81.449%.
Another example would be "OFFPEAK_TARGET": "u8_64" which, following the above logic, results in a unsignd int of 8 bits or a byte. 64 in hex represents 100 in decimal.
The last one would be "STAT_HOURS_OF_OPERATION": "u3_0000183E" which is a 32bit/4 byte unsigned integer. After conversion from hex to int this value reads 6206 hours of operation.
Custom functions for an ESP32/Arduino
To convert a fl_ value I am using the following custom function. This function uses a union to cast the bit values of a byte array into a float value and atoh() to create decimal values from the hex strings. (see comments inline)
float convertFloat(const char *text){
//create a union to easily cast values into another type
union floatData{
byte by[4];
float fl;
} dataValue;
//get number of bytes (4 for float values)
byte bytes = (strlen(text)-3)/2;
//filling the byte array
for(int i=0;i<bytes;i++){
dataValue.by[3-i]=atoh(text[2*i+3]);
dataValue.by[3-i]=dataValue.by[3-i]<<4;
dataValue.by[3-i]=dataValue.by[3-i]+atoh(text[2*i+4]);
}
//returning the byte array as a float through the union.
return dataValue.fl;
}
//hex string to decimal
unsigned char atoh (unsigned char data){
if (data > '9')
{ data += 9;
}
return (data &= 0x0F);
}The same for 8bit uint8 / u8_:
byte convertByte(const char *text){
union byteData{
byte by;
} dataValue;
byte bytes = (strlen(text)-3)/2;
for(int i=0;i<bytes;i++){
dataValue.by=atoh(text[2*i+3]);
dataValue.by=dataValue.by<<4;
dataValue.by=dataValue.by+atoh(text[2*i+4]);
}
return dataValue.by;
}And also for 16bit int / u1_:
int convertInt(const char *text){
union intData{
byte by[2];
float in;
} dataValue;
byte bytes = (strlen(text)-3)/2;
for(int i=0;i<bytes;i++){
dataValue.by[1-i]=atoh(text[2*i+3]);
dataValue.by[1-i]=dataValue.by[i]<<4;
dataValue.by[1-i]=dataValue.by[i]+atoh(text[2*i+4]);
}
return dataValue.in;
}And also for 16bit int / u3_:
unsigned long convertUnsignedLong(const char *text){
union inData{
byte input[4];
unsigned long output;
} dataValue;
byte bytes = (strlen(text)-3)/2;
for(int i=0;i<bytes;i++){
dataValue.input[3-i]=atoh(text[2*i+3]);
dataValue.input[3-i]=dataValue.input[3-i]<<4;
dataValue.input[3-i]=dataValue.input[3-i]+atoh(text[2*i+4]);
}
return dataValue.output;
}Now you should have gotten the hang of it. The other values can be translated in the same manner. Just put the Hex values into a byte array and then cast it to the wanted datatype using a union. Maybe one could even create a funktion which decides the correct datatype on its own.
In my next post I can hopefully present you my full implementation of a Senec status display using a LED matrix and an ESP32.
