RE: Another nRF5 based wall switch
J1 is http://www.tag-connect.com
Range is ok for my setup (wall switch and gateway are not too far away from each other), but this is one of the things I want to improve. I will also consider an additional capacitor to decrease the internal resistance of the voltage source. Do you know, if there is anything inside the Ebyte module? I couldn't find any information/schematic. However I need to understand the sleep current and the drawbacks on the battery choice before I build an improved version.
You are so right and this is my #1 goal with this proof-of-concept. Unfortunately I'm not there yet... Regarding remote control you mean the machnical actuation of the switches? Yes, why not.
Another nRF5 based wall switch
I'm currently looking into possible solutions for wall switches with high WAF;)
According to my wife, I'm already quite close, so I want to share my current project status with you and thank all contributors to MySensors.
My wall switch is mechanically based on http://haus-bus.de The multi push button switches integrate nicely with the Busch Jäger Reflex SI switches, I already have at home.
I created my own electronics based on the nRF52832 module from Ebyte.
Besides the Ebyte module, I only have inductors for DCDC mode, a CR2032 battery and the switches on the PCB. The switch cover is semi transparent, so LEDs might be added to give some visual feedback.
With the CR2032 battery the PCB is quite shallow, so I was able to extend an extisting conventional wall switch by using a double frame.
My measurements show a sleep current of 12 uA, so the battery should be good for about one year. However the nRF52832 should be capable of much less sleep, so I still need to work on that issue.
If anybody is interested in some more details, I'm happy to share the information.
I've built a wall switch based on Nrf52832 and MySensors 2.2.0. It uses 6 push buttons, so I defined 6 sensors sending messages, when a push button is pressed.
When I define the sensors as S_DOOR and send V_TRIPPED messages, it works as expected. But when I define the sensors as S_BINARY and send V_STATUS messages, it takes a few seconds until the message is received at the gateway. Changing to S_BINARY and V_TRIPPED eliminates this lag, so it is somehow related to the V_STATUS definition.
Is there any explanation for this behavior?
