Hello Radek,

today SPOT prices: https://www.ote-cr.cz/cs/kratkodobe-trhy/elektrina/denni-trh?date=2023-05-31

Two cheapest hours block start at 13:00:00 and stop at 14:59:59. Now is 14:15 and block is still off. Four cheapest hours block start at 11:00:00 and stop at 14:59:59. Time is 14:15 and block is on.

It looks like the blocks are shifted by two hours. Timezone is UTC +2 / Central European Summer Time (CEST).

Attributes of 2_hours_block and 4_hours_block:

There is some other problem in hours blocks. 2 hour block was in On state in last week (25.5. - 31.5.) only 3 times.

4 hour block was in On state in last week (25.5. - 31.5.) only 5 times.

It happened to me as well now ... though block sensor's attributes Start/End show correct values, sensor value is not changed. I saw an error in log (below) - probably short network outage. After reloading the integration everything is fine and values switched immediately. Is it possible to have a sensor reflecting that all the stuff is reloaded correctly ? Or any other way of detecting this issue ? Maybe the processing is stopped after this error occurs and the switching part is skipped while we have all the required info to do so.

This error originated from a custom integration.

I believe this is fixed in 0.6.0. It was caused by failing to fetch the data from OTE servers which then fail to update the update the actual sensor value.

Please reopen if you still see the problem.
