Additional information about your setup (OctoPrint version, OctoPi version, printer, firmware, octoprint.log, serial.log or output on terminal tab, ...)

Who can't read T and B? Or is that an error that you are getting somewhere? What's in the logs?

You really need to give more context to this.

i post here

https://discourse.octoprint.org/t/cant-display-hotend-and-bed-version-1-3-9/4856/2

Don't post in multiple sections, since you posted this in development, are you asking for help writing a plugin / developing something for octoprint?
