Wifi instead of bluetooth #31

Do you think you can make this work via wifi instead of bluetooth at some point?

Hi. My recuperator does not have a wifi and i am not planning to buy a new one in near future.

I read on https://github.com/zauan/hassio-prana (i think) that the wifi connection is encrypted and can't be reversed engeneered. I asked many times to info@prana24.com to develop an integration for esp home or, at least, to open a local web server (or socket server) to handle local requests.

Maybe more people harassing prana service could give us more possibilities

Then i should start doing that i just got 2 of them installed today, both are WiFi enabled.

Why don't just use bluetooth? Or they are wifi only?

Gruffuss commented 14 hours ago

No, they are not WiFi only and i am going to use bluetooth for now, but frankly... I sadly don't have the available sockets to plug esp32s close to the prana devices

I got 3 units with bluetooth+wifi and will disable wifi when all the local setup using the esphome+HA will work fine. I don't see the point in keeping enabled it. I will never update the firmware after such switch: it could just break the bluetooth compatibility.

The plug for the esp32 can stay even at 6-10 meters away from the Prana unit. Don't worry!

Wifi range is longer than ble one. If they could open something over wifi it's meaningless to develope it using espHome

I investigated about the wifi implementation. The unit periodically pushes data on a remote MQTT server and pulls command requests. This means that it is cloud based and you need WAN connection to make it work. All these details are unofficial and a potential implementation could break in any moment. I would not spend too much time on the wifi-side if you are interested in a HA integration. IMHO
