I've been busy with a project to water all my plants in the greenhouse.
The system is stand alone with a water tank instead of a connection on the water mains. So first the program has to check if the water level is not low, this to protect the waterpump.
If the water level is ok, the irrigation sequence can start with a delay for the pump to build up pressure. Then 8 valves are sequentialy opened and closed after another. The delays can be changed to determain the amount of water every valve is providing.
And I also want to monitor the temperature and humidity.
Evereything is working now, except the temperature and humidity, i can monitor them by serial print, but it is not visible in Domoticz. Please help me with this last detail.
Code: Select all
/* Z-kas
* Z-wave controlled irrigation system for greenhouse.
* Input: watertank level
* temperature (DHT22)
* humidity (DHT22)
* Outputs: waterpump switch (z-wave)
* 8 valves for 8 water circuits
* 8 valves for different irrigation
*
* When irrigation is started by user or timer in Domoticz:
* Measure waterlevel
* When waterlevel is not low start pump
* After ... seconds start valve sequence
