Detect KNX bus power down

[tpospichal]

Hello is there any way how to catch KNX bus power loss by event script?

For example my LM has a power backup, but KNX Power source does not, so after power restores i need to run some scripts.

Thank you.

Try this

Code:

function check()
  local delta, wdt
    wdt = io.readfile('/tmp/tpuart.wdt') or ''
    wdt = tonumber(wdt) or 0
    delta = os.time() - wdt
  return delta <= 10
end

checktp = check()
log(checktp)
