QuickApp - SolarEdge Live (Modbus) version 1.2

[SmartHomeEddy 1,005]

This is the next version 1.2 of the SolarEdge Live (Modbus) QuickApp.

The SolarEdge Live (Modbus) QuickApp represents an advanced integration that provides instant, real-time access to local inverter data without the limitations of cloud-based API’s. This QuickApp uses the Modbus of your SolarEdge Inverter to get the real-time information about your SolarEdge setup. The QuickApp reads the SolarEdge SunSpec Modbus registers and shows the with QuickApp variables requested register values in child devices and labels. The QuickApp runs at an interval setup in the QuickApp variables. A special button is available to adjust the speed up the interval.

Enabling Modbus on SolarEdge Inverters: 
To enable Modbus communication on a SolarEdge inverter, follow these general steps:

• Access the inverter’s configuration menu, either via its control panel or through the manufacturer’s configuration app.
• Navigate to the communication settings.
• Enable Modbus support, selecting TCP/IP for network connections.
• Adjust Modbus parameters as needed, such as device ID and communication port.
• Save your changes and restart the inverter if required.

After activation, the inverter is ready to communicate with external systems or monitoring solutions using the Modbus protocol. Always consult your inverter’s user manual for detailed instructions specific to your model.

Changes version 1.2 (2nd September 2025)

• Changed the main device type to com.fibaro.powerMeter, so it can contain the AC Power value. 
• Added QuickApp variable for the main device register, mainRegister (default = 40084 AC Power). 
• Added default don't 'Save events to History' (saveLogs = false) to the setup of every child device. 
• Disabled the warnings for READ, WRITE and Invalid response. Users can't prevent those errors and to display them as warnings only clutters the logging. 
• Changed the text of the interval speed buttons to the content of the quickapp variables intervalChildsS, intervalChildsM and intervalChildsF. 
• Found a few old SolarEdge Modbus QuickApp names in the code and changed them also to SolarEdge Live. 
• Optimised the register mapping. 
• Changed the default interval timing to 60, 10 and 5 seconds. Of course, you can use your own settings. 
• Removed the expiration date. 

 

Changes version 1.1 (9th August 2025)

• Renamed the QuickApp from SolarEdge Modbus to SolarEdge Live. SolarEdge Live represents the QuickApp in a better way. Of course the Modbus is still used as protocol.
• Added button for 'Inverter' with support for SunSpec model type 101 (single phase), 102 (split phase) or 103 (three phase). 
• Added QuickApp variable inverterType for the model type of your Inverter (101 (single phase), 102 (split phase) or 103 (three phase), default type 101 (single phase). Also see the value of register 40070.)
• Added optimisation with re-use of the already connected Modbus socket. 
• Improved memory usage with more variables as local variable. 
• Changed the maximum retries to a maximum consecutive time no response. 
• Changed the interval to three speeds, Slow, Medium and Fast. With QuickApp variables the speeds setting can be made for the interval and child updates. 
• Added an indicator (*) to most of the buttons to show what selection is active. 
• Added 'Disconnect' (or 're-connect') button to manually disconnect the QuickApp and Modbus. 
• Added extra check for the amount of addresses (including the extra scale factor addresses) not to exceed 125 (Modbus spec: max 125 registers per request). 
• Added extra check for the addresses being in the 40001-49999 range. 
• Changed the register table to indexed, so the addresses (and scale factors) can be selected directly and fast from the table. 
• Removed a double warning for CONNECT issue. 
• Added in case of a device type 'com.fibaro.energyMeter' the property 'storeEnergyData = false' is added to the setup of that child device. By default the energyMeter won't save energy to the energy database.  
• Added in case of a device type 'com.fibaro.powerMeter' the property 'includeInEnergyPanel = false' is added to the setup of that child device. By default the powerMeter won't be used for instantaneous power in Energy Panel calculations.  
• Added the current time to the log text of the main device. 
• Added the register address to the log text of all the child devices. The log text was empty. This will help to get more acquainted with the register addresses. 
• Placed the register address in front of the label text to make it more readable. 
• Improved the message of the retry warnings, show seconds to maxResponseTime. 
• Improved some register description text. 
• Rounded all the values to two decimal places. 

 

Changes version 1.0  (27th July 2025)

• Initial version with child devices to configure in QuickApp variables. 

 

Variables (mandatory and created automatically): 

• host = Modbus TCP IP address of your target device (default 192.168.1.145)
• port = Modbus TCP port (default 1502)
• unitId = Modbus slave/unit address (default 1)
• inverterType = Type of your Inverter (101, 102 or 103, default type 101. Also see the value of register 40070.)
• intervalS = How fast the Modbus will refresh the data (Slow default 60 seconds) 
• intervalM = How fast the Modbus will refresh the data (Medium default 10 seconds) 
• intervalF = How fast the Modbus will refresh the data (default 5 seconds) 
• intervalChildsS = How fast the Childs will update (Slow default 60 seconds)
• intervalChildsM = How fast the Childs will update (Medium default 10 seconds) 
• intervalChildsF = How fast the Childs will update (default 5 seconds) 
• maxResponseTime = Maximum time in seconds for response of the Modbus to disconnect (default = 60)
• debugLevel = Number (1=some, 2=few, 3=all) (default 1)
• Also with the QuickApp variables child devices can be created. Insert a QuickApp variabel with the address as 'variable' and the deviceType as 'value'. By default the values from the childs will show in the labels (except Scalefactor values). You can use all kinds of devicesTypes, for example: 
• com.fibaro.energyMeter (Wh) (by default no storage to energy database)
• com.fibaro.powerMeter (Watt) (by default not used for instantaneous power in Energy Panel calculations)
• com.fibaro.electricMeter (Volt and Ampere)
• com.fibaro.multilevelSensor (Number values)
• com.fibaro.temperatureSensor (Temperature)

First it was space in child device type!

Variable can not be deleted.

ah, great. But you can't delete the variable?

 

 

(If you change the number in the variable, SAVE and change it back, you also get the right child)

I did changed the value and changed it back, and it worked.
