Hello everyone, I’m currently exploring ways to control a couple of Hunter magnetic valves in my garden. The challenge is that I don’t have WLAN availability where the valves are located, only 230V AC. I’ve come across a couple of potential solutions but I’m curious to hear if anyone has other ideas or experiences to share.
First, I considered placing a second Raspberry Pi in the garden and connecting it via a 433MHz transceiver. This setup would use a standard 8x relay card to switch the valves. While this seems feasible, I’m wondering if there’s a more efficient or cost-effective alternative.
Another option I found is the Homematic Wireless Switch Actuator, specifically the 4-channel DIN rail mount version. This would require purchasing an addon card for the Raspberry Pi since I don’t currently have a Homematic CCU. I’m curious if anyone has experience with this setup or if there’s a simpler way to integrate it without additional hardware.
I’d love to hear if anyone has successfully implemented a similar solution or if there’s a different approach altogether. Maybe there’s a smarter way to handle the wireless communication or a more straightforward device that could simplify the setup. Any insights or recommendations would be greatly appreciated!
