Currenttransformer with 3 windings, can I adjust the range to its new value?

by termeerh on

I would like to measure my solar energie production with a higher resolution.
This can be done by making 3 windings trough the current transformer but how can I adjust the range from 50 A to 16,667 A?

The sensor.lua-file seems the place of the drop down list in the FLM's config page:

  1. current = s:option(ListValue, "current", translate("flm_current"))
  2. current:value("50")
  3. current:value("100")
  4. current:value("250")
  5. current:value("500")
  6. current.rmempty = false

It's also in the config file flukso.uci itself
  1. config sensor 1
  2.         option id 0123456789abcdef0123456789abcde1
  3.         option type electricity
  4.         option class analog
  5.         list port 1
  6.         option voltage 230
  7.         option current 50
  8.         option enable 0

The other code does not seem to fix the clamp's current to above values...
Perhaps that easy to change it by ssh'ing into the FLM...

But note that in the AVR-code the meter constant is an integer

  1. uint16_t meterconst;

Thus try it with either 16 or 17; good luck and tell your results ;-)
