Adding text at home assistant sensor

[diego065]

Hello everyone!
I would like to add some custom text to the sensor value that is displayed.. any idea on how to do that?
To be clear, I have a sensor showing the temperature after the 8x8 bitmap but I also would like to add something like "External {value from HA} °C "... until now I couldn't find any way to show on the display all the information I want.
I tried as the attached picture but it only shows me one info!
Thanks in advance

Hi,
I always do this with a "Function Node".

This could then look like this:

But there is also the syntax (which I also prefer):

Thanks! What's the differences between the 2? It will be also possible to "combine" two different attributes or sensor?

Also interested in combining two variables in one screen.

I usually don't do this in NodeRed, but in my case in ioBroker.

The values of two different sensors could be combined like this:

[{"id":"c4132efe91eeaf68","type":"inject","z":"a9932bcf1db982ed","name":"","props":[{"p":"payload"},{"p":"topic","vt":"str"}],"repeat":"30","crontab":"","once":false,"onceDelay":"0,1","topic":"","payload":"","payloadType":"date","x":150,"y":80,"wires":[["22e1feab934f8c26"]]},{"id":"22e1feab934f8c26","type":"api-current-state","z":"a9932bcf1db982ed","name":"","server":"6b1fc163.10009","version":3,"outputs":1,"halt_if":"","halt_if_type":"str","halt_if_compare":"is","entity_id":"sensor.temperature_wetterstation_balkon","state_type":"str","blockInputOverrides":false,"outputProperties":[{"property":"temp","propertyType":"msg","value":"","valueType":"entityState"}],"for":"0","forType":"num","forUnits":"minutes","override_topic":false,"state_location":"payload","override_payload":"msg","entity_location":"data","override_data":"msg","x":470,"y":80,"wires":[["28f0f00d43d49258"]]},{"id":"1ca8885cc2e0e944","type":"debug","z":"a9932bcf1db982ed","name":"debug 1","active":true,"tosidebar":true,"console":false,"tostatus":false,"complete":"payload","targetType":"msg","statusVal":"","statusType":"auto","x":500,"y":200,"wires":[]},{"id":"28f0f00d43d49258","type":"api-current-state","z":"a9932bcf1db982ed","name":"","server":"6b1fc163.10009","version":3,"outputs":1,"halt_if":"","halt_if_type":"str","halt_if_compare":"is","entity_id":"sensor.humidity_wetterstation_balkon","state_type":"str","blockInputOverrides":false,"outputProperties":[{"property":"humid","propertyType":"msg","value":"","valueType":"entityState"}],"for":"0","forType":"num","forUnits":"minutes","override_topic":false,"state_location":"payload","override_payload":"msg","entity_location":"data","override_data":"msg","x":470,"y":140,"wires":[["d910d3cab965072c"]]},{"id":"d910d3cab965072c","type":"function","z":"a9932bcf1db982ed","name":"function 1","func":"msg.payload = `${msg.temp}°C ${msg.humid}%`;\nreturn msg;","outputs":1,"noerr":0,"initialize":"","finalize":"","libs":[],"x":360,"y":200,"wires":[["1ca8885cc2e0e944"]]},{"id":"6b1fc163.10009","type":"server","name":"Home Assistant","version":4,"addon":true,"rejectUnauthorizedCerts":true,"ha_boolean":"y|yes|true|on|home|open","connectionDelay":true,"cacheJson":false,"heartbeat":false,"heartbeatInterval":"30","areaSelector":"friendlyName","deviceSelector":"friendlyName","entitySelector":"friendlyName","statusSeparator":"at: ","statusYear":"hidden","statusMonth":"short","statusDay":"numeric","statusHourCycle":"h23","statusTimeFormat":"h:m"}]

Content of Function1 Node:

msg.payload = `${msg.temp}°C ${msg.humid}%`;
return msg;

---

The difference between:

msg.payload = "External " + msg.payload + " °C"

and

msg.payload = `External ${msg.payload}°C`

Is that the first one uses string concatination and the second one uses a template literal.
When writing clean code, the second one is prefered.

String concatination can, in some edge cases, result in wierd outputs.
