It would be perfect, if I could connect not only 8 valves but 8 moisture sensors too. Then I could setup watering for valve no.1 at monday from 4:00 AM (but only if in section 1 is soil moisture under 100), to 6:00 AM (but only if soil moisture 300 will not be reached sooner).
It is very simply and eco friendly saving of water.
Please, could you think about it? Moisture sensors are very cheap now and you can do only expansion sensor board, something like for valves.
