Error when changing to 24h

[MrGlad8]

Ok so I followed closely your guide on how to change to 24h. But after changing the part in the automation I get this error when trying to run the automation: Error: Error rendering data template: TypeError: %d format: a real number is required, not str Any ideas whats wrong? :)

Can you upload your weatherman sensor yaml and your automation yaml for us to look at - it's difficult to guess.

This is occuring as your time coming into the automation is probably still a string, and it's expecting a decimal - the %d is d for decimal.

[MrGlad8]

Sure, here is the template: https://dpaste.org/DDMA4 And here is the automation: https://dpaste.org/GP0hS

Are the variables in the code right? Aren't those suppose to be added in the automation as its own building block like before the action?

Just tested your config and it works fine. The only time I got that error was if I changed my times to "not 24h" versions. If I use your time format in your Weatherman Data Tag sensor (%H) it works perfect. When changing the time format, you do need to refresh your template entities (https://YOUT_HA_INSTALL/developer-tools/yaml) at the bottom, and also either wait 15 mins, or change the /15 in your weatherman sensor to /1 to make it update every minute, not 15, and then wait 1 minute and try below -

Can you send me what you get if you find your Weatherman Data Tag entity in the State page (https://YOUT_HA_INSTALL/developer-tools/state). You should get something like below. Check that your wm_time_0, 1,2,3 are showing as numbers:

I'm sorry I'm probably doing something wrong. But I cant get it to work. But if I leave the code as it was before in the automation: {{ state_attr('sensor.weatherman_data_tag','wm_time_0') | string | upper }} It actually works.. I see 24 hour on my display.. no errors.. so I dont know hehe.

Here is the state of the weatherman entity:

I see yours ends with _forecast but I guess you made your own and not like the one in the guide?

[chunkysteveo]

The _forecast is just my sensor. I guess if yours works without the formatting, it's a win!!

Can we close this off? And your other issue?

[chunkysteveo]

OK, as found in another issue - we need to update the automation script for the times, for time_0,time_1,time_2,time_3 to the following (replacing wm_time_0 with 0,1,2,3 etc based on the time attribute you are printing):

{{ '%0.2d' | format(state_attr('sensor.weatherman_data_tag','wm_time_0') | int) | string | upper }}

Note the inclusion of the | int in the line of code, which is missing in your automation, and causes an error.
