Atlas Scientific EZO I2C Adapter for ioBroker

This ioBroker Adapter integrates several Atlas Scientific EZO Devices https://atlas-scientific.com/ into your own ioBroker environment. The EZO devices have to be configured for I2C Bus and have to be mounted on a device (e.g. RaspberryPi..) with configured and enabled I2C Bus.

Currently Supported Devices

Future Support

  • Please create a feature request issue, if you think about further implementations

Getting started

Installation

Especially make sure, that you have properly configured and enabled I2C on your system (if needed):

Setup Adapter

After the Adapter installation and the preconfiguration on the RaspberryPi you will find the new Adapter in the Instaces Section where you can further configure your sensors.

Image

With a click on the wrench icon a new settings window will appear, pre selected with the "General" Settings Tab.

Here you have to insert the I2C Number into the Textfield which has been configured on the Raspberry Pi (0 or 1). Afterwards you can press the "Device Search"-Button to search for all connected EZO circuits. The detected device-addresses will be listed on the left hand side.

Image

With a click on one of the detected devices the "unconfigured" device screen appears.

Image

Click the dropdown menu to select the type of your desired device.

Image

After you`ve selected the type of device the settings screen for the desired device appear. Repeat those steps for each device you want to use.

Image

General Configuration (all devices)

  • Address: Non adjustable (except change of IP Address)
  • Device Type: Desired Device Type Dropdown
  • Name: Name of the Device stored on the device later on (Whitespace will be removed. If longer than 16 characters, only the first 16 will be sent.)
  • Polling Interval: Interval in milliseconds for the device value polling. If > 0 the device will be reading all values in this intervall. Please increase the intervall time when you will receive wrong readings. I suggest at least to start with 15000ms
  • Active Switch: Switch to enable or disable the use of that sensor
  • LED Active Switch: With this setting you can enable or disable the LED on the EZO Device

Common Functionalities (all devices)

  • "Find EZO Board"-Button -> With a click on this button the LED on the EZO Board starts flashing fast.
  • "Factory Reset"-Button -> Execute a factory reset for that device
  • "Change I2C Address"-Button -> Here you can program a new I2C Address for that adapter. Please make sure you save the config afterwards.

Common States / Objects (all devices)

Some states have a state change detection mechanism running which gives the possibility that some values can be set not only by the Admin UI but additionally with changes directly to the state value from outside. (e.g. via Script or manually) This can be useful for example if you want to use comepsation values from a sensor like temperature to adjust the temperature compensation value on the PH Sensor.

  • "IsPaused" -> Switch to temporarely pause all measure readings from Device unless it is "Actice" during runtime. true = paused, false = measurements active. Value is defaultet to false (measure active) on Adapter Start/Restart.

Run Scripts per Javascript-Adapter Instance

In some cases it is helpful to make the use of javascript code execution. I have added some examples to the repository including description.

Image

Example 1: Get Substrings from DO Sensor Value related to active Params mg/l & %

This script is created for use in the "Script execution" JavaScript adapter. The data points must of course be adapted to the local setup The script splits the value string supplied by the DO sensor, which can contain mg/L as well as % depending on the activated parameters, into two values and stores them in two data points.

Image

Example 1 Script
 console.log('Start');

 const DO_mg_L = 'javascript.' + instance + '.DO_Sensor.DO_mg_L';
 createState(DO_mg_L, 0, {"type": "string", read: true, write: false, role: "value.do", unit: "mg/L"});
 const DO_Percent = 'javascript.' + instance + '.DO_Sensor.DO_Percent';
 createState(DO_Percent, 0, {"type": "string", read: true, write: false, role: "value.do", unit: "%"});


 function buildSubstrings(str, start, end) {
 const arr = str.split(',');
 console.log('Array:' + arr.toString());
 return arr; 
 }

 on({id: 'atlas-scientific-ezo-i2c.0.0x61.Dissolved_Oxygen', change: "any"}, function (obj) { 
 
 console.log('Value changed: ' + obj.state.val);
 const doString = obj.state.val;
 const result = buildSubstrings(doString, 0, 1);
 console.log(result.toString());
 
 // Only mg/L
 if(result.length === 1){
    console.log('Setting state DO_mg_L: ' + result[0].toString());
    setState(DO_mg_L, result[0], true);
 }
 // mg/l & %
 else if (result.length === 2) {
    console.log('Setting state DO_mg_L: ' + result[0].toString());
    setState(DO_mg_L, result[0], true);
    console.log('Setting state DO_Percent: ' + result[1].toString());
    setState(DO_Percent, result[1], true);
 }
 });

Example 2: Set the Temperature compensation for several Sensors

This script is created for use in the "Script execution" JavaScript adapter. The data points must of course be adapted to the local setup It checks the temperature values supplied by the RTD sensor, truncates the decimal places to 1. If a change from the old to the new value occurred, the temp_compensation states of the desired (target) sensors are set with time offset

Image

Example 2 Script
 console.log('Start temp compensation Script');

 const ph_temp_compensation = 'atlas-scientific-ezo-i2c.0.0x62.Temperature_compensation';
 const do_temp_compensation = 'atlas-scientific-ezo-i2c.0.0x61.Temperature_compensation';

 on({id: 'atlas-scientific-ezo-i2c.0.0x63.Temperature', change: "any"}, function (obj) { 

 const newTemptring = obj.state.val;
 const oldTempString = obj.oldState.val;
 const newTempCut = parseFloat(newTemptring).toFixed(1);
 const oldTempCut = parseFloat(oldTempString).toFixed(1);

 console.log('Temp value received: Old:' + oldTempCut + ' New:' + newTempCut );

 if(!(newTempCut === oldTempCut))
 {
    console.log('Temp changed from ' + oldTempCut + ' to' + newTempCut );
    console.log('Setting state ph_temp_compensation: ' + newTempCut);
    setStateDelayed(ph_temp_compensation, newTempCut, 5000);
    console.log('Setting state do_temp_compensation: ' + newTempCut);
    setStateDelayed(do_temp_compensation, newTempCut, 8000);
 }
 });
