Intex Pure Spa wifi control

Hi, i bought Intex Pure Spa with wifi enabled control panel.

I did not found any intergration for it so far.

So i installed their android app and started sniffing on network. It talks to port 8990 and communication is not encrypted. For example, after pushing “filter” icon in app, it sends something like

{"data":"8888060F010004D4","sid":"1626776247245","type":1}

and device responds with

{"sid":"1626776247245","data":"FFFF110F01030019000000008280801F000020","result":"ok","type":2}

Using telnet and repeating this string, it also switches the filter pump.

I will try to dig into it, no promises.

Btw. it is ESP device. It has telnet port open to everyone and says something about FreeRTOS in prompt
