Is the purpose to read the API only or also providing controls?

i'm working on a project creating an generic library to read/write JSON Api's, this would be a potential candidate. If there is any chance to have credentials for testing purpose w can consider looking at it

Hi, did anybody succeed in testing the local api with something like netcat? I can connect to my marstek venus (the local api was enabled within hours by the support on simple request in feedback). This means, I dont get connection refused, with is given on other ports. Using json from the examples in the api docs returns .... nothing. Any help? In the first step I like to read the SOC, other use cases like controlling might follow ...

@harvey637: i assume you need a "-l" option in nc. UPD is a single shot protocol und then the marstek needs a receiver to deliver the answer. (i don't own this battery, but would like to buy it, but only if the API is running)

Do you have an example of the MQTT output?
