Spark - Non-time-based windows are not supported on streaming DataFrames/Datasets;

I need to write Spark sql query with inner select and partition by. Problem is that I have AnalysisException.
I already spend few hours on this but with other approach I have no success.
Exception:
Exception in thread "main" org.apache.spark.sql.AnalysisException: Non-time-based windows are not supported on streaming DataFrames/Datasets;;
Window [sum(cast(_w0#41 as bigint)) windowspecdefinition(deviceId#28, timestamp#30 ASC NULLS FIRST, RANGE BETWEEN UNBOUNDED PRECEDING AND CURRENT ROW) AS grp#34L], [deviceId#28], [timestamp#30 ASC NULLS FIRST]
+- Project [currentTemperature#27, deviceId#28, status#29, timestamp#30, wantedTemperature#31, CASE WHEN (status#29 = cast(false as boolean)) THEN 1 ELSE 0 END AS _w0#41]
I assume that this is too complicated query to implement like this. But i don't know to to fix it.
SparkSession spark = SparkUtils.getSparkSession("RawModel");
Dataset<RawModel> datasetMap = readFromKafka(spark);
datasetMap.registerTempTable("test");
Dataset<Row> res = datasetMap.sqlContext().sql("" +
" select deviceId, grp, avg(currentTemperature) as averageT, min(timestamp) as minTime ,max(timestamp) as maxTime, count(*) as countFrame " +
" from (select test.*, sum(case when status = 'false' then 1 else 0 end) over (partition by deviceId order by timestamp) as grp " +
" from test " +
" ) test " +
" group by deviceid, grp ");
Any suggestion would be very appreciated.
Thank you.

I did not. I implemented from beginning with different approach. I used custom aggregation.
