Resolved but not fully. The situation now is following. I have two devices connected to DI_2 and D_3. They show the same value as expected as they measure the same power line. Nevertheles DI_1 increasing the value as well even without connected device. Its value is aproximately a half of the DI_2 and DI_3. I made no changes on debounce time. Possibly bug in evok?
