508 II R8 MyPeugeot App remote control climate launch by Arduino

MyPeugeot App is not operate well, many times App sent message "not connection". I use app by Samsung S21 phone.

I think make control system by Arduino WiFi by LTE 4G USB modem with Wi-Fi HotSpot system. Have You got best ideas to do it, please? I read some stories to read CAN-data by Arduino program, here is link to Arduino PSA Diag My Peugeot App is new version 1.51.1 and it is update and new version have more buttons for lighs, doors and horn. They not operate, may be E-x008 models, but Peugeot is not get information of uppdate.

Not Arduino, but SMS wake up to CAN-data.

Have somebody idea to drive/control climate remote without My Peugeot App? Switch relay some place to turn on main connector, water pump, heater and blower. Maybe some LIN or CAN code to data-bus...
