How to build an overridable MySensors relay based device (e.g. lamp with manual switch)
-
Hmm - that's interesting. I've been looking at the Sonoff stuff since you posted this, thanks!
One of my goals is to have no Internet connectivity to my devices, and it looks like there are some firmware options that would let me achieve that. So that's a plus.
The minus so far is that I can't find anything about range extenders / relay (signal, not power) for these. Two of my early use cases are out of WiFi range, so I'd like to be able to have something between the shed and the controller that acts as a relay. One of the things that attracted me to MySensors is that nodes can act as relays for other nodes.
Do you know if that's possible with Sonoff ?
@anonymouslemming I am not even sure this would work because I am not sure about how the 433MHz side of the Sonoff RF's work, but what about adding a repeater of some sort to your setup. Something like this

I know this may sound weird, but I would recommend just going with the basic Sonoff switch and skip the MySensors part.
I build a lamp controlled by MySensors a long time ago, has external Tact button for on/off. Works great, took a while to build and I have an ugly box screwed to my lamp now that houses it all.
I wanted to build another, but didn't want it be be aesthetically displeasing. I ended up using these (https://www.itead.cc/sonoff-wifi-wireless-switch.html) and they are everything in one small package. You have wifi, a tact button for manual on/off, and it will report to any home automation system using MQTT after flashing some customer firmware (https://github.com/arendst/Sonoff-Tasmota). Just cut the power cable, screw into appropriate terminals and it's all good to go.
As much as I love MySensors; for this type of project I think there is a better solution.
