HomeAssistant tries to convert everything coming from a "sensor" node to float

[valueerrorx]

Right before i updated HA i was able to use a sensor node to send strings like "on" and "off" (or "high" "mid" "low" and other things) to HA and it would display the string right away next to the icon.

now HA tries to convert everything to float and obviously fails to convert "off" to float - therefore it throws an exception and shows "unknown" next to the icons.

is there a way to configure a sensor node so that HA knows it should just display the received value as string instead of converting it? or ith there another way (another node) i could use for this purpose?

thank you for your work! this palette is very helpful

this is where all of this is needed: https://gitlab.com/valueerror/drexel-weiss-node-red-flow

This is the HA error. After the last update to 6.3 it wants to convert it to int not to float. i don't get what's happening here.

There are changes in the sensor components of HA

You need to upgrade this plug-in, and then clear the Unit of measurement of the sensor node, The string status can only be used when the Unit of measurement is empty

wow... that was quick :-)

in order to update it i had to ssh to my node-red raspi (there was no update visible in the web-ui)

cd .node-red/
npm update node-red-contrib-ha-mqtt   
sudo reboot

thank you very much - it works like a charm! if you could add a paypal qr code i would love to buy you some drinks ;-)
