inteParticipantHello Ray,
connecting humidity or soil moisture sensors is also a great idea.
I hope you will include patches for the devices you connected at one point that it will become easy to implement for all users!
Cheers,

inteParticipantHello Ray,
I’ve already ordered one of the DIY kits you still have in stock.
I understood those still come with a relay so I will be fine 🙂
My order will probable need some time for shipping and customs, and I will have to build it as well, so I guess I will be back here in a couple of month to ask for assistance on how to connect the RF modules…
I decided for the Opensprinkler over the OsPi because I think I won’t need (another) full featured Linux box on my network which I have to keep updated with security updates.
My Idea with the 433Mhz receiver is to mount a RF switch next to a water outlet which I can use to open/close the corresponding valve. I would consider that a quite common scenario, or what would you think?
Thanks,Chris

inteParticipantGetting a bit more confused…
After further reading I found a mention in the blog that DIY-products will be discontinued. Ok, fair enough, so HW-rev 2.1u seems to be the last version available,
Searching in the forums I found that the relay functions was removed in rev 2.3 and is not available in the DC version. Sad.
Reading the OsPi manual I learned that the recent OsPi-version seems to feature analogue ports for humidity sensors e.g. now, so the website is obviously outdated.
Searching the forums I found some threads discussing the LCD screen for the OsPi, so it seems possible.
However, I guess I will go for the DIY-AC-variant then, seems to fullfill my needs.
I only wonder if it was not only possible to add a 433Mhz transmitter (e.g. to control sth.) but also a receiver, e.g. to receive a signal for opening a valve on demand (as I pointed out in my previous posting).
EDIT: OK, this seems possible. But is it also possible to connect both, a transmitter AND a receiver?
Thanks in advance regarding the other questions! -
