And to my question about the possibility of connecting it to the PC with some software they replied that it is not possible but without giving me any explanations...

In reality, Vevor does not sell any module compatible with this inverter, and when I asked Vevor assistance about the module suitable for this inverter, they told me that it is not available and they don't know when it will be... As always, useless answers from Vevor. ..

Thank you for the lesson but I know how to use the tester... However, I am convinced that the wifi dongle I purchased, a wifi plug pro 05, is not compatible with this inverter, the voltages are there but the dongle does not communicate, it is not a question of power but of incompatibility in my opinion

On pin 5 I have no voltage, on pin 4 and pin 8 negative or 12.8v on pin tx or +12v approximately most likely my unit has some problem on the port...

I followed this diagram so it's not right pin 4 should be 5?

I tried to connect a wifi plug pro 05 but the com light doesn't come on, could you make the pin diagram work? I would be grateful...

That software called smartess is available for Android

Here is the response from vevor assistance: Dear Customer, Thanks for the reply. Modbus protocol, with CRC data calibration. If you have any further problems, please feel free to contact us. Congratulations.

I did something by taking a stripped rj45 cable and measured we have 4 pins, two 12v power supplies and the other 2 rx tx respectively, I found approximately 12v and 25v... I don't know if it can be useful but shouldn't it be +12v and - 12v?

Vevor support just replied telling me that it won't work with other wifi dongles, you need the specific one for this inverter and for the moment it's not available, most likely it has a proprietary protocol that not even they know about... However, they were unclear in the description... If you have news, update me

Hi, I'm writing from Italy, I'm in the same situation as you, I'm trying to connect it to a wifi plug pro but it doesn't communicate, I've tried various configurations of the rx tx pins etc but nothing, I wrote to Vevor assistance and from what I'm understanding they don't even know , I opened a ticket for a non-working item, anyway the inverter works very well, the only problem is the door that can't communicate, let's keep updated ok?
