If I add a 250Ω resistor across the 4–20mA output (+/−), the voltage across it should become 1–5V (max 5V at 20mA), so it should be measurable by 0–5V analog input. Is this correct and supported?

I’ve connected the CLOB, but I don’t know when the data is received. Can the timing be set?

what you want to do? monitor analog data?

I solved it by manually fetching the data every 2 seconds. Is there a better approach?
alias: COLB - Poll analog (A_FF) every 2s
mode: single
triggers:
- seconds: /2
trigger: time_pattern
actions:
- data:
topic: COLB/xxxxxxxxxxxx/set
payload: "{State=A_FF}"
action: mqtt.publish
