Hi everyone, I’m Ahmed, and I’m currently working on integrating my Nuki lock with an existing DIY home access system based on Raspberry Pi. The goal is to control my garage and yard doors using the Nuki Fob alongside my current setup. While the initial setup worked smoothly, I encountered an unexpected issue with electromagnetic interference (EMI).
Here’s what happened: I soldered two wires to the Nuki Fob’s push button terminals and connected them to a relay controlled by my Raspberry Pi. The idea was to mimic the push button action, allowing the Nuki lock to perform locking and unlocking operations based on the relay’s state. Everything seemed to work perfectly at first. However, I soon noticed that whenever an electrical device like a water boiler or AC doorbell was nearby, the fob would activate unintentionally.
This issue persisted even after I rechecked and resoldered the connections to ensure there were no wiring errors. It appears that the fob is sensitive to electromagnetic waves emitted by nearby AC devices. I’m now seeking advice from the community—has anyone encountered a similar problem while working on DIY home automation projects? If so, how did you resolve it? Any insights or suggestions would be greatly appreciated!
Thanks in advance for your help. I’m really looking forward to hearing from you all.
