Hello everybody,
I got a problem that even ChatGTP has no answer for...
I got a MCP3008, channel 0, CS0 SPI0 with LDR and got it working with Python.
With Node-Red I used RPI-a/d converter with a debug to read (result: statusVal = "")
I tried all the channels, CS and bus without any result.
Somebody please.......

What node did you use?
Else [try this one](https://flows.nodered.org/node/node-red-node-pi-mcp3008) special for the MCP3008

I used this node, and tried all possible settings.
What is the difference between Node-Red and Python (by Thonny) both on the same RPI4
On Node-Red works everything, DS18b20 dig in and dig-out are all working.
Thanks for the reply😀
