Hi,
I am using a growatt inverter. This growatt app works fine. I have a wifi-s module attached to my inverter. I reflashed another wifi-s module to esphome. That works also great. But the problem is that I can’t use both wifi-s modules at the same time. So I can’t use the shinephone app AND esphome home assistant interface at the same time. I am a design hardware engineer and want to solve this problem. I want to make wifi-s module that has 2 esp07s modules. 1 for esphome and the other one with original software. Where can I find the schematic of the wifi-s module?
I will use a atsamd21g18 that controls the data management to the growatt inverter. It will provide the data to both modules with its usarts. Can someone with the schematic of the wifi-s pcb or at least the pinout of the wifi-s connector? That would be great. I will make a PCB for this and keep you up to date if I have more information.
I would be very grateful if you can provide some information. Thanks in advance.
Best regards,
Erik
I cannot help you but I am interested as to the ‘why’ you want two dongles at the same time?
I make this, so my growatt module also keeps reporting the data to growatt and I can see on home assistant and shinephone what my solar system generates at the same time. if home assistant is offline, I still can see the data from growatt. plus both modules are updateable and function like the original modules.
Iam currently doing the same using grott which sends data to Ha and fwd to growatt, using a single non flashed shinedongle
