## Water meter with IZAR module (Diehl IZAR RC 868 I R4 PL)

24

![diehl_metering](https://github.com/zibous/ha-watermeter/blob/master/docs/diehl_metering.jpg)

+

28

+

I did some experiments with **wmbusmeters**, **DVT SDR_STICK**, **NANOCUL** and ended up with: **ESPHome - ESP32 (v4) + CC1101**.

29

+

30

+

With the NANOCUL solutions, I always had problems with the USB input and with the high resource consumption on the NUC or Raspberry computers.

31

+

32

+

33

+

34

+

## ESPHome + ESP32 (v4) + CC1101

35

+

36

+

ESPHome - ESP32 (v4) + CC1101 is the best solution for me because the resource requirement is low.

### Requirements

48

+

49

+

- Water meter with IZAR module (Diehl IZAR RC 868 I R4 PL),

50

+

IZAR Radio Compact Hall is designed for mobile reading and fixed network remote reading of Diehl Metering meters.

51

+

52

+

- [ ESP32 Dev Kit C V4 NodeMCU](https://amzn.eu/d/eUNLyYc)

53

+

- [Fayme CC1101 868MHZ Funk ÜBertragung Antennen Transceiver Modul, Grün](https://amzn.eu/d/i5YwBkR)

54

+

Alternative: [ EBYTE TI CC1101 Wireless 868Mhz 915Mhz RF Modul](https://amzn.eu/d/7GPqsng) with external antenna.

## ESP8266 vs ESP32 (v4)

110

+

The version with **WEMOS D1MINI (ESP8266)** was my first version. WEMOS D1MINI (ESP8266) has only limited RAM and can only be used to a limited extent. If there are too many sensors and the logger level is to high, a **JSON memory error occurs**, which causes the device to restart again and again.

111

+

112

+

__Note__: The **ESP32** has more RAM memory and is therefore better suited for use. To prevent this, it is absolutely necessary to set the log level to `warn`. Otherwise, at a higher log level, JSON errors will occur in productive operation.
