Water meters. Heat meters. Energy meters. In the direction of which protocol and data collection server to look?

Question

linux

So that all this riot works together and centrally collects data. Maybe someone will tell the manufacturer all this at once. So as not to produce a zoo. Webmord at the server is required. Like the network interface of the "brains"

Answer 1

As a developer and user of the "Smart Apartment" system, I will share the following information:
1) Electric meter: Mercury 202 or 230. Preferably with RS-485 immediately, so as not to buy converters. For transfer to the server, the simplest RS485-> USB with aliexpress for 100 rubles is suitable.
2) Water meters with a pulse output (they cost 300r more than usual)
3) The heat meter is also either a pulse or RS-485. A good model was somewhere in the bookmarks. Heat meters are generally expensive. 10-20k cook.
We connect all this to the controller, I have it Atmega328, and then we transfer it to the server for processing and storage
Oh yes, the budget of the entire smart apartment is 100-150k, provided that everything is mounted and configured by yourself. Those who talk here about the budget of 700k just want to cut down the dough on the "dummies".

There is an interesting article about collecting data from water meters - https://geektimes.ru/post/254968/

Answer 3

The counter itself, as a rule, cannot communicate with the network and the site, but if we talk about centralized monitoring, then it must have some kind of interface.
1) The counters themselves have a machine-readable interface.
2) A set of interface converters - devices capable of converting the meter interface to the one you need
. For example, convert RS232 to a regular LAN.
They will collect data from the meters and send it to you on the network in the format that you set.
3) Data collection server - its own server that will receive data from meters in the specified format, enter them into the database, organize an interface for users, etc.
There are hundreds of manufacturers of meters and interface converters.
Choose the ones you need for the price and functionality, buy and set up.
And write the data collection server yourself to collect data in the format that you configure on the equipment.
