In an industrial environment, are you only using single phase? often it's 3 phase 415/440 volts (can't remember the exact RMS and tolerance levels) and you may need to be more aware of wiring regulations... > Can be better to move to i2c? I've seen some "power and energy measurement > IC", even from Maxim, with I2C bus, but it will be totally new for me. My local ham repeater group have had good success using field-effect on their DC (solar + batteries) sites - don't know if they work on AC. I suspect you may be back to using torrioidal coils around the feeds (what most of the metering uses anyway) and modern meters will have either RS485/ethernet/modbus interfaces in most plant rooms - see https://plus.google.com/111912984393205202430/posts as an example Not saying you CAN'T do it with owfs, but it may not be the most appropriate tool... ------------------------------------------------------------------------------ Try New Relic Now & We'll Send You this Cool Shirt New Relic is the only SaaS-based application performance monitoring service that delivers powerful full stack analytics.
