how often it update the data send ? does have instant power update ?

The energy meter will upload data to IAMMETER-cloud every 1 min. If you need more fast uploading,there are many options 1 use the modbus tcp ,you can request data every 1 second. https://www.iammeter.com/newsshow/news-modbus-tcp-energy-meter 2 use the local API ,you can request data every 6 seconds. https://www.iammeter.com/docs/integrate-with-PVOutput 3 develop your own server and do not use IAMMETER-cloud, then you can upload data each 6 seconds(to your own server) https://www.iammeter.com/docs/own-system

Hi, Is it possible for current sensors to be delivered to me to measure 250A or 500A?

Hello, sorry, we only have 150A meters on Amazon. I have already replied to you with an email. Please kindly check! Thanks. Best Regards, Steven Lu

I've got a panel with 3 individual phases 127vac/60hz (not delta, not wye), can i use this device to monitor them? can you share a link with a manual?

please refer to https://www.iammeter.com/docs/wiring-diagram

can you measure power factor and kwh demand?

Hi, this product can measure pf. About the kwh demand, I think it should be calculated by the cloud service ,not the hardware. Our cloud have not provided such function now(calculate kwh demand), maybe we will consider upgrade our system to provide such feature if more customer have this requirements.
