Thank you for answering my question and thank you for all the articles on your blog. It is appreciated!
Thank you for the kind reply and your interest in our articles about metering. It’s always rewarding to hear that people are finding them useful.
Please can you tell me the difference between an event and an alarm? Can you give me a real example of each that a CLOU meter will produce?
Thank you for your question. I suggest you read the article about event logs. In general, an alarm can be triggered from each event, but not each event is worth to trigger an alarm. The individual configuration is always done with the utility to meet their specific needs.
My concern is the mode of data acquisition from the meter to the HES bearing in mind the cost.
Which communication method would you recommend and why?
When we consider the annual operational costs, the power line communication (PLC) is still the most cost-effective way to connect domestic energy meters with the head end system. With all other methods you are in the hand of telecommunication companies for each single node. Some IoT solutions are coming up, but I haven’t seen dedicated carrier costs so far. Maybe you take a look at the article “Smart Meters and the Internet of Things“.
Please I’m Paul from Benin republic Cotonou precisely someone tampered with my meter so it’s not connecting again please how can fix it back
You need to inform your local power supply company. They can give you a clear tamper token.
