Just is case some other newbees (like me) around, made one also for sensors (as need those values as well in several scripts), combined above advice and Homey example-script:

> \_.myReadSensor = async function (sensorName, capabilityName) {  
> const devices = await Homey.devices.getDevices();
> 
> for (const device of Object.values(devices)) {  
> if (!device.capabilitiesObj || device.class !== ‘sensor’) continue;
> 
> ```
> if (device.name === sensorName) {
> const sensorCapability = device.capabilitiesObj[capabilityName];
> if (sensorCapability) {
> return sensorCapability.value;
> } else {
> return null; 
> }
> }
> 
> ```
> 
> }  
> return null;  
> }
