When the Shelly UNI is configured using all the default Channel and link informa…tion the _VoltageADC state shows as Err in the UI: ![ADC](https://user-images.githubusercontent.com/84638697/119236498-0ae0cf00-bb38-11eb-9f2a-526831e15f69.png) ## Expected Behavior The Item should be created in a way that allows the display of the STATE using the default parameters ## Current Behavior In order to get the STATE to display correctly the metadata for State Description has to be modified to something like ```%.2f V``` This allows the STATE to display correctly (and consistently with the behavior of the Shelly EM: ![ADC2](https://user-images.githubusercontent.com/84638697/119236609-a2462200-bb38-11eb-9d32-4ea87bad40d0.png) This has been discussed on the forum under: https://community.openhab.org/t/oh3-shelly-binding-uom-voltage-vs-temperature-explanation/122624 Seems that on the Shelly UNI the UoM is not included in the state: ``` { "link": "http://localhost:8080/rest/items/ShellyUNIshellyunie8db84d6b3e510163199230_VoltageADC", "state": "27.83", "stateDescription": { "pattern": "%.0f %unit%", "readOnly": true, "options": [] }, "editable": true, "type": "Number:ElectricPotential", "name": "ShellyUNIshellyunie8db84d6b3e510163199230_VoltageADC", "label": "Shelly UNI Voltage ADC", "category": "", "tags": [ "Point" ], "groupNames": [] } ``` Whereas on an EM, the UoM is included: ``` { "link": "http://localhost:8080/rest/items/ShellyEMshellyemb04c0810163199229_Voltage", "state": "232.1 V", "stateDescription": { "pattern": "%.3f %unit%", "readOnly": true, "options": [] }, "editable": true, "type": "Number:ElectricPotential", "name": "ShellyEMshellyemb04c0810163199229_Voltage", "label": "Shelly EM UPS Voltage", "category": "", "tags": [ "Point" ], "groupNames": [] } ``` ## Possible Solution Could the Binding be updated to include the UoM on the Voltage ADC channel, similar to what is done on the Shelly EM? ## Steps to Reproduce (for Bugs) 1. Link the _VoltageADC channel using the default Type (Number:ElectricPotential) 2. View the linked ITEM on the UI ## Context Inconsistent behavior between different Shelly products as well as difficulty for new users who expect that the ITEM will display correctly when configured using the default settings. Requires the addition of Metadata to overcome. Also inconsistent with other linked channels such as Temperature which also do not require additional metadata to work "out the box". ## Your Environment Version used: openHAB 3.1.0.M4 Environment name and version: Java Runtime Azul Systems, Inc. 11.0.9.1 (Zulu11.43+55-CA) Operating System and version: Windows 10/10.0 (amd64
