Today, ASCUE systems are gaining great popularity. And this is not surprising, there is a huge advantage in automatic energy collection and control systems - access to data on the current readings of all meters of an apartment or country house can be obtained in 1 click.

  First, let's look at working with single-tariff metering devices. These include the majority of water meters and half of all electricity meters. We should immediately note that it will be possible to take readings only from devices equipped with a pulse output. The SE 8i module allows you to monitor up to 8 metering devices. In this article, we will look at connecting and configuring all devices.

   Let's take Mercury 201.5 as an electricity meter.

As a water meter - BETAR SGV-20D.

 Connection

  In counters, we need a pulse output to connect. Each output must be connected to the SE 8i module at terminals Point0-7 and GND. The schematic diagram of the connection is shown below.

Setting

1) Addressing

  By default, the SE 8i module is displayed as a single device. Depending on the number of connected metering devices, in addition to the SE 8i module, additional SE PulseCounter virtual devices may appear in the system, one for each connected metering device. Thus, if the address displayed on SE 8i is 1 and we collect readings from 8 metering devices, then an additional 8 SE PulseCounter devices with addresses will be created in the system. 2, 3, 4, 5, 6, 7, 8, 9. The addresses of the created devices will strictly depend on the input of the module. For more information on how to calculate addresses, see the table below (where A is the address of SE 8i).

Module Input SE8i Light	Address of the virtual counter SEPulseCounter
Point0	А+1
Point1	А+2
Point2	А+3
Point3	А+4
Point4	А+5
Point5	А+6
Point6	А+7
Point7	А+8

  When addressing modules, consider creating virtual devices. When the SE PulseCounter addresses are superimposed on the addresses of other modules, AlphaSE Hub2 will not be able to work with them. 

2) Configuring the number of SE PulseCounter virtual devices

   The first step is to set the number of counters that we will poll. After that, restart the power hub. It will poll all the modules again. In our case, it will detect one SE 8i device with address 30 and 2 more SE PulseCounter devices with addresses 31 and 32. 

   After restarting the hub, new devices will appear.

3) Setting events for pulse counting

   Next, you need to determine in which mode the module input will work. According to the instructions in the Mercury 201.5 meter, it is necessary to count the openings. To do this, make the following settings:

4) Setting up a permanent tag

   Next, you need to specify the number of pulses per kWh. In the instructions, this characteristic is called the "Counter constant". It is specified in the instructions for the device, but quite often it is duplicated on the device itself. For Mercury 201.5 meters, it is equal to 3200. Since the readings on the device itself are displayed with 1 decimal place and we want to see the same readings in the application, we will specify the meter constant 320 instead of 3200 in the device settings.

5) Setting the pulse duration

   Metering devices emit pulses with a duration of 10 to 50 ms during operation. By default, the inputs of the SE 8i module have a duration of 100ms. For this reason, it needs to be changed. The pulse duration in the settings of our SE 8i module should be such that it does not take into account possible leads, but also does not skip pulses from the meter. We specify a duration of 10 ms. if the readings are considered correct, then this setting should be left on an ongoing basis.

6) Number of decimal places

   In the application, we want to show 1 decimal place. It was with this in mind that we previously specified the Counter Constant in the settings.

7) Current readings

   Next, we indicate the current meter readings along with our decimal place. Let's assume the current meter reading is 9412.0. 

  The BETAR SGV-20D counter is configured in the same way only for Point1.

8) Names for indications

  The next step is to specify the names for the meter readings. To do this, configure the SE PulseCounter with the address 31

Display

     Upon successful configuration, the meter data will be displayed on the management page. The following are examples of displaying readings in Smart Electronics and Yandex applications.

   From multi-tariff metering devices, data is no longer collected through a pulse output, but via a digital bus. Due to the fact that each manufacturer uses its own data transmission protocols, the data collection device must be compatible with the metering device. To receive data from the CE102 multi-tariff electricity meter (versions S6, R5, S7, R8, R8Q, S7J), it is necessary to use the SE CE102 smart home module. One module allows you to read up to 16 readings. For example, it can be the total tariffs of 16 different meters or the data of 4 tariffs from 4 different meters.

   The SE CE102 module can be defined by the controller as 17 different devices – the SE CE102 module itself and up to 16 pcs. SE PulseCounter (pulse counter). All SE PulseCounter modules have the following addresses after the main address of SE CE102.

   The metering devices are interrogated via the RS485 interface using the CE protocol. Detailed information about the exchange protocol can be obtained on the website of the meter manufacturer.

   When the SE CE102 expansion module receives a request from AlphaSE Hub2, it transmits the request to the metering device, then forwards the AlphaSE Hub2 response. In order to reduce delays during hub operation, the SE CE102 module requests data from the meter no more than once every 10 seconds. The rest of the time, it sends the data previously received from the meter. If the metering device does not send a response to the expansion module more than 10 times in a row, the expansion module stops transmitting responses to the AlphaSE Hub controller until communication with the metering device is restored. Thus, information about the lack of communication with the metering device is transmitted to the AlphaSE Hub2 controller.

Setting

1) Number of tariffs to read

   After connecting the module, you first need to specify the number of tariff readings that we will poll. In our case, there will be only one counter and 3 tariffs - Tariff 1, Tariff 2 and Amount.

2) Tag addresses

   Since the SE CE102 module polls tariff readings over a bus that can contain even hundreds of meters, for each tariff we read, we need to specify the address of the meter from which we plan to receive it. In Energy Meter meters, the address is the last 5 digits of the serial number. The address of the counter shown in the photo is 59249. We assign it to the addresses of the counters for the first 3 readings.

3) Tariff numbers

   The next step is to specify the tariff number that will be queried for each of the readings of the SE CE102 module. 

4) Names for indications

   Next, in each SE PulseCounter module, you need to specify a name for the indication.

5) Reboot and check

   After completing the configuration, you must restart AlphaSE Hub2 on power. It will poll all the modules again. In our case, it will detect one SE CE102 device with address 1 and 3 more SE PulseCounter devices with addresses 2-4..

  Congratulate. The setup is complete.
