MQTT Provision #11

Open xianrecords2015 opened 4 years ago

Hello,

Thanks for making this project. I started my own with a standard MCP3208 but found that a 12bit ADC is not accurate enough. I like the approach of the CS5490.

I have a question for you. In the driver.js, I saw that you have some provision for MQTT but I could not find anywhere on the configuration web page a way to enter the MQTT server, username, password and port. Am I missing something ?

Thanks

Chris

It’s not exposed by default. Add ‘?advanced=1’ to the url and you should see it

Thank you for your answer,

I was trying to analyze the CS5490.js and forgive my ignorance and little knowledge of Javascript but you are requiring a CS5490 at the beginning of the code. I am assuming that this is not the CS5490.js file itself. There are a number of call to a cs5490 library (ie: cs5490.DigitalRead) that I cannot reference. Where are they coming from ?

Also you have define 4 input pins to read the HW version. I have a hard time to find them on the schematics. I can find the output pins but I am not understanding the inputs.

Thanks

Christian

I now understand the 4 input pins for HW version.

I also see that you have developed a CS5490 C++ in one of the other branch that I believe is what you require in the cs5490.js. I am wondering in the setup file how you import it in the project and the setup

The 4 input pins are to determine the hardware version of the boards. There are drivers written in C for both the CS5463 and CS5490 chips. They use nanhttps://github.com/nodejs/nan to interface with the node based PiPowerMeter software.

There seems to be some inconsistencies in the V4 Schematics/Board.
