Hase-iQ

Example communication to a Hase iQ Stove. https://www.hase.de/iq-technologie

Sample Program

Python program ofen.py connects to the oven and request all known commands in different intervals. Displays all kown values to the console. Example Output

Communication

Communication is unencrypted websocket text. Text payload is ascii encoded base64.

Client sends a request for a command by sending "_req={cmd_name}". Server (the stove) sends back "{cmd_name}={value}". Example: Send "_req=appT" and you receive "appT=511.3". See example down below for more details.

Known Commands

commandsCurrentState

        "appPhase",         #current phase. enum: 0=idle 1=heating up 2=burning 3=add wood 4=dont add wood 
        "appT",             #temperature in celsius
        "appAufheiz",       #heating percentage - on first heating it seems to correlate with target temperature 475c. doesnt seem to only correlate with temperature afterwards
        "appP",             #performance in percent
        "appNach",          #??? always zero?
        "appErr",           #error state

commandsStatistics

        "appPTx",           #length of availabe 1min performance history - should start at 0 on first heatup, goes to max 60
        "appP30Tx",         #length of availabe heating cycle performance - if 30 cycles are reached it should stay at 30
        "appPT[0;59]",      #performance history of last 60min
        "appP30T[0;29]",    #performance history of last 30 cycles
        "appIQDarst",       #?intensity of iq logo during stop adding wood dialog in app?

commandsInfo

        "_oemdev",          #stove model - enum: 6=sila (plus)
        "_oemver",          #controller version
        "_wversion",        #wifi version
        "_oemser",          #serialnumber
        "_ledBri",          #led brightness

Example

Want to request current Phase by using command appPhase

Request should look like this: "_req=appPhase"

Encode this string in base64 ascii: "X3JlcT1hcHBQaGFzZQ=="

Add a ascii carriage return at the end: "X3JlcT1hcHBQaGFzZQ==\r"

Websocket raw text payload to send: "X3JlcT1hcHBQaGFzZQ==\r"

Answer from stove as payload text: "YXBwUGhhc2U9NA==\r"

Decoded from base64 ascii: "appPhase=4"
