rRFXMeter is a B4XLib for sending RFXMeter value (ULong) from microcontroller, via 433Mhz Transmitter, to a RFXCOM RFXtrx433e device connected to Domoticz Home Automation System. The goal is to send sensor & actuator data from an Arduino Microcontroller to Domoticz Home Automation System by using a RFXCOM RFXtrx433e transceiver.
  • This project has started by finding a solution to read the flow temperature of a home heating device and log the value in Domoticz.
  • Create a fit-for-purpose solution for sending all kind of sensor & actuator data to be handled by a Domoticz single device acting as a dispatcher (router).
  • Explore 433Mhz communication between Microcontroller & Domoticz RFXtrx433e.
  • Arduino connected modules tested: 433Mhz Transmitter, DHT22 (Temperature & Humidity), Reed Switch (Contact), Thermosensor MAX6675 (Temperature), SlidePot (Dimmer).
  • Develop the solution with B4R & Domoticz dzVents Automation Events.
  • The solution has been developed for personal use only. Use at your own risk.

1649582403154.png Solution The Arduino microcontroller sends RFXMeter messages to the Domoticz Home Automation System via a cheap 433Mhz transmitter. The Domoticz Home Automation System, running on a Raspberry Pi, has a RFXCOM RFXtrx433e Transceiver connected to an USB port. The RFXtrx433e transceiver receives the RFXMeter message and sends the message to Domoticz RFXMeter device (Hardware RFXCOM RFXtrx433e). A Domoticz Automation Event (dzVents) listens to RFXMeter device changes, converts the message data and updates associated Domoticz device(s) or any other action. The RFXMeter message data send is an unsigned long (ULong) value with range 0 - 16777215 (HEX FFFF, 3 Bytes from ULong data type). It is also possible to send data to various Domoticz RFXMeter devices and handle Automation Events accordingly. The RFXMeter device acts as a trigger to update other devices (or take any other action). The ULong value contains packed information used by the Automation Event dzVents. Example: A temperature & humidity module DHT22 is connected to an Arduino UNO. The measured temperature 19 C is sent to a Domoticz RFXMeter device with address 09 and assigned via dzVents to temperature device with IDX=375. The value sent is 1337519: 1 3 375 19 - 1=Leading Number (fixed), 3=Length IDX, 375=IDX, 19=Temperature. The dzVents script listens to device changes with IDX=384 (the RFXMeter), parses the RFXMeter sValue (ULong 1337519) for the device (IDX=375) and updates the device sValue (19). Snippet: return { on = { devices = { 384 } }, execute = function(domoticz, device) local idxlen = tonumber(string.sub(device.sValue, 2, 2)) -- 3 local idx = tonumber(string.sub(device.sValue, 3, 3 + idxlen - 1)) -- 375 local svalue = tonumber(string.sub(device.sValue, 3 + idxlen, -1)) -- 19 domoticz.devices(idx).setValues(0, svalue) end } The B4R development environment offers a variety of libraries for sensors & actuators. This allows to build modular solutions. Heads Up As mentioned, this is a fit-for-purpose solution and has limitations given by the ULong value (0 - 16777215) sent from the microsontroller. This means depending requirements, checks or workarounds needs to be developed accordingly.

Examples RFXMeter Data for Sensors & Actuators
  • Temperature: Value Range 0 to 100; Send as value 0 - 100; Domoticz takes the value without conversion.
  • Temperature: Value Range -10 to 10; Send as value 0 - 20; Domoticz converts with offset 10 (0=0-10=-10, 20=20-10=10).
  • Humidity: Value Range 0 - 100; Send as value 0 - 100; Domoticz takes the value without conversion.
  • Switch: Value Range 0 - 1; Send as value 0 (=Off) or 1 (=On); Domoticz takes the value without conversion.
  • Up-to 7 Switches: Value Range 1NNNNNNN with N holding switch N state 0-1; Send as 10101101 with 1 as leading for the ulong value; Domoticz converts the switches states and assigns to respective switch devices.
  • Device: Value Range depends on IDX & value; Send the value to a device with given IDX. Example: 127841 (1 2 78 41) - Leading 1 followed by IDX length 2 for the IDX 78 with value 41 (max 9999); Domoticz converts the value in IDX and value and assigns the value to the device with the IDX.
  • Dimmer: Value Range 0 - 100; Send the value to a device with given IDX. Example: 1338652 (1 3 386 52) - Leading 1 followed by IDX length 3 for the IDX 386 with value 52 (max 9999, but for the dimmer is 100); Domoticz converts the value in IDX and value and assigns the value to the device with the IDX.

Why RFXMeter? An RFXMeter is a remote RF sensor transmitting encoded data from electric power, water, gas, or other metering devices. Domoticz supports RFXMeter devices connected to the hardware RFXCOM - RFXtrx433 USB 433.92MHz Transceiver. The Domoticz device type is RFXCOM with subtype RFXMeter counter. The device supports the types Energy, Gas, Water, Counter, Energy Generated and Time. The type counter is selected which supports type unsigned long (4 Bytes) from which 3 bytes are used (see next). The ULong value holds the sensor or actuator data. B4R Code Module RFXMeter The B4R solution has a B4R code module RFXMeter to send the device address, value. The code module is based on the function RFXMeter from the X10RF-Arduino open source project. If packed in a B4X Library, then the B4XLib contains the code module RFXMeter which does not need to be declared in Process_Globals. Methods Init the RFXMeter RF433 transmitter and LED. tx_pin - Signal pin of the RF433 Transmitter led_pin - Signal pin of the LED indicating data is send (0=disabled) B4X: Initialize(tx_pin As Byte, led_pin As Byte) Send value to the RFXtrx433e device. The address parameter enables to send to a dedicated Domoticz RFXMeter device. addr - Address of the RFXMeter device used as ID in Domoticz. Example: 0x09 (Domoticz ID: 09F9). value - Long range 0 - 16777215. B4X: SendValue(addr As Byte, value As ULong) Send a command to the RFXtrx433e device. data - array as byte with max length 6, i.e. data=09F98EE40501 for an address=9, value=364260. B4X: SendCommand(data() As Byte) Send an array of bytes to the RFXMeter. addr - Address of the RFXMeter device used as ID in Domoticz. Example: 0x09 (Domoticz ID: 09F9). data - Array of bytes. Example: array as Byte(1, 2, 3). B4X: SendBytes(addr As Byte, data() As Byte) Send an array of max 7 bits (value 0 or 1) to the RFXMeter. The ULong value is max 7 bits + leading 1 = 8 Bits (like 11111111). The bits can hold the state of switches, lamps, security devices. addr - Address of the RFXMeter device used as ID in Domoticz. Example: 0x09 (Domoticz ID: 09F9). data - Array of bits. Example: Sending 5 Switches with state packed in the ULong value of 111010 (with leading 1) = Array as Byte(1,1,0,1,0). B4X: SendBits(addr As Byte, bits() As Byte) Send value (ULong) to the Domoticz RFXMeter device which is used to set value of a Domoticz device with given IDX. RESTRICTION: The longer the IDX number length, the smaller the device value to stay with max number length of 8. For larger values use method Send instead. addr - Address of the RFXMeter device used as ID in Domoticz. Example: 0x09 (Domoticz ID: 09F9). idx - IDX of the Domoticz target device. This is not the RFXMeter device but the Virtual Sensor like Temperature device. value - Device value The value sent to Domoticz has following pattern: 1 = 1 - allways for leading the value. 2 = IDXLEN - Length of the IDX. Example: IDX 78 has length 2. 3 to 3 + IDXLEN - 1 = IDX of the target device. Example: 78 3 + IDXLEN to length value = Value. Example: 41. The max value is 9999. Examples: 127841 (1 2 78 41) - Leading 1 with IDX length 2 for IDX 78 with value 41 (max value 9999). Total length of the value sent is 6 (max 8). 13123999 (1 3 123 999) - Leading 1 with IDX length 3 for IDX 123 with value 999 (max value 999). Total length of the value sent is 8 (max 8). 13123499 (1 4 1234 99) - Leading 1 with IDX length 4 for IDX 1234 with value 99 (max value 99). Total length of the value sent is 8 (max 8). B4X: SendValueToIDX(addr As Byte, idx As Int, value As ULong) Note The library contains in addition some experimental methods which are worked upon. These are not listed here. Fields MAX_VALUE = 16777215 (as ULong) Max value transmitted. The max value are the first 3 bytes of the ULong value: HEX=FFFFFF, DEC=16777215. MAX_BITS = 24 (as Byte) Max number of bits transmitted. The max value is 24 bits (3 bytes of the ULong value: 11111111 11111111 11111111). MAX_BYTES = 3 (as Byte) Max number of bytes transmitted. The max value is ULong 3 Bytes FFFFFF. MAX_NUMBERS = 8 (as Byte) Max number of numbers transmitted is 8. The number needs to be kept below max value 16777215. Example bit pattern 11111111 for switch states. SIGN_POS = 1 (as Byte) Positive sign used for example for temperature device SIGN_NEG = 2 (as Byte) Negative sign used for example for temperature device Repeats = 5 (as Byte) Number of send command repeats. The recommended value is 5 repeats. Logging = False (as Boolean) Set logging to the serial line. Example Logging to the B4R IDE: B4X: RFXMeter: Send address=9, value=16807 RFXMeter: Send Address Bytes 0,1=09F9 RFXMeter: Send Value Bytes 4,2,3=0041A7 RFXMeter: Send Packet Type&Parity Byte 5=08 RFXMeter: SendCommand data=09F941A70008 Hard-/Software

1649582429520.png Files rRFXMeter.zip archive contains the class and B4R sample projects. Install The library file rRFXMeter.b4xlib is installed in the B4R additional libraries folder. From the zip archive, copy the content of the library folder, to the B4R additional libraries folder keeping the folder structure. B4X: <path to b4r additional libraries folder>\rRFXMeter.b4xlib For B4R program examples, lookup folder Examples. The B4XLib contains the code module RFXMeter which does not need to be declared in (for example) Process_Globals. Wiring B4X: 433Mhz Transmitter = Arduino UNO VCC = 5v Signal = #7 GND = GND Domoticz Configuration The RFXMeter has to be added to the Domoticz devices. This can be done by adding new hardware in the Domoticz GUI: GUI > Setup > Settings > Hardware/Devices option Allow for 5 Minutes. When running the Arduino program, the device is added with the address set to the Domoticz hardware RFXCOM - RFXtrx433 USB 433.92MHz Transceiver (Version: Ext2/1025, Name: RFXtrx433e). Example new RFXMeter with IDX set by Domoticz, address 09F9, hardware RFXtrx433e: B4X: IDX=384, Hardware=RFXtrx433e, ID=09F9, Unit=0, Name=RFXMETER, Type=RFXMeter, SubType=RFXMeter counter, Data=NNNN The device has the initial name Unknown and from type Counter. Lookup the GUI > Tab Utility > Device Unknow to change the properties via Edit. The name changed to RFXMeter. To hide the device from the GUI tabs (like Utility), set the the name to $RFXMeter. Depending requirements, several RFXMeter devices can be defined - ensure each has a unique address. Examples The first examples simulate a device which value is sent to Domoticz and handled by an Automation Event dzVents. In addition, a DHT22 Temperature & Humidity module example is given. More examples in the folder Examples, like Reed Switch, Thermosensor MAX6675. Example Basic (Simulation) This basic example sends a random generated value from an Arduino UNO to the Domoticz RFXMeter device (as created previous).

  • Hide the RFXMeter from the Domoticz tabs: Put $ in from of the device name, i.e. $RFXMETER instead RFXMETER.
  • For tests delete device history: http://domoticz-ip/json.htm?type=co...idx=382&fromdate=2022-01-01&todate=2022-12-01
  • When using multiple Domoticz devices connected to the same RFXMeter device, ensure to select the right device in the Automation Event(s) dzVents or define multiple RFXMeter devices assigned to virtual sensors. This to avoid data clashed when RFXMeter device is updated.
ToDo
  • Add more sensor & actuator examples
  • Consider receiving 433Mhz signals to trigger actuators or change settings like timer intervals.
