I’m interested in the DFRobot Wido Arduino board - it looks like it has a connection for an external antenna and I might want to add one given the characteristics of the building I’m going to install it in.
Is that the case? I can find no mention of it on the internet.
I find myself tempted to an R.Pi simply because it is easier to choose from a variety of low-cost wifi interfaces with aerials etc, but I worry about the resilience for long-term use and occassional power cuts - I’m planning to put it where it will be rather inconvenient to access, and want something that will ‘just work’ (operating relays) for a long time, even if power is intermittent and there is no orderly shutdown.
I’m wondering whether I should just go with the DFRobot Leonardo with the XBee socket, so I have a choice of modules and power for comms. I’m not bothered about the wireless technology - I have wireless APs at the moment but I’d like the sensor/actuator system to be independent of them.
(Its a shame Z-UNO is so expensive, having a Z-Wave gadget with XBee form factor would be handy, especially if it was cheap and would act as a mesh repeater. Partly that’s why R.Pi looks attractive - I can add Z-Wave USB and have a repeater/listener for Z-Wave devices)
