can't make summarise out of tsibble grouped object

[jimoreira]

HI, Trying to use this tool. I'm able to get the tsibble object from an irregular timing dataframe with: *i have no key

weather_x <- x %>% 
  as_tsibble(
    index = date_n_time,
    regular=FALSE)

the result

> weather_x
# A tsibble: 4,198 x 15 [!] <UTC>
   date_n_time         temperatura humedad potencial_matriz mojado_hoja mojado_text
   <dttm>                    <dbl>   <dbl>            <dbl>       <dbl> <chr>      
 1 2022-04-07 19:44:57        21.7    70.1            3861         1005 seco       
 2 2022-04-07 19:51:03        21.6    70.5            3774.        1005 seco       

But, when i try to get regular intervals and summarise i get only one value, and not one fore every hour (in the hourly example). According to the next code.

weather_x2<- weather_x %>%
  index_by(date_hour = ~round_date(., unit = "1 hour")) %>% 
  summarise(temp=max(temperatura))

if i just get the object with the grouping produced by index_by it works ok and produces the next result.

> weather_x2
# A tsibble: 4,198 x 16 [!] <UTC>
# Groups:    @ date_hour [431]
   date_n_time         temperatura humedad potencial_matriz mojado_hoja mojado_text
   <dttm>                    <dbl>   <dbl>            <dbl>       <dbl> <chr>      
 1 2022-04-07 19:44:57        21.7    70.1            3861         1005 seco       
 2 2022-04-07 19:51:03        21.6    70.5            3774.        1005 seco

If somebody has any idea of how to solve this would be appreciated. Would love to use this package and I get stuck at the beginning.

Thanks!!
