£9, that's cheap :) Here in Denmark we pay around 150kr (which is about £17,5 with the current exchange rate) as a fee, just for the courier to handle the duties and paper work.
Wow that's insane. I promise I won't complain anymore when DHL adds around 10$ for that (other express services do not).
Sometimes local post adds a fee, but it's like once every 20-30 envelopes, and only 20 000VND = less than 1$ :)@Nca78 said in Sensebender Europe resellers ?:

For gateway you could use any arduino uno with or without a w5100 network or an esp8266 if you are just doing tests
ah, I wasn't aware of that. Are there any docs that demonstrate how to build a gateway using that ?
That might work out cheaper in the short term to see if this is a viable solution for what I want to do.

Nice - ta.
Does this sound like the full list of parts for my one lamp test project then:
Gateway
- Arduino
- W5100 module
- NRF24L01+ radio
Sensor
- Arduino
- NRF24L01+ radio
- Relay
Am I correct in saying that all of these items except the relay need 3.3v at most ?
My plan would then be to purchase 2 x Arduino micros so that if all goes well and I graduate to SenseBender for the gateway, I could reuse the second micro in a second sensor.
Any glaring issues with that list / plan?
Thanks in advance!

If you don't need battery powered sensors, you could use the 5V Arduinos.
That mean adding a regulator to my parts list above, right ?
I'm not considering any sensors at the moment, I just want to be able to trigger the lamp. So cost is the driving factor.
There are just so many parts to consider at https://www.mysensors.org/build/connect_radio#shopping-guide . I'm fairly handy with a soldering iron, and happy to just breadboard it for the initial work, so I wasn't planning on getting any of the solder free options until I started seeing how cheap they are there :)

If you use arduino nanos you don't need any regulators. they have 3.3V for the NRF24L01+ and 5V for the relay.
You even don't need an ethernet shield if you connect the gateway via USB to your controller (Raspberry pi, ...)This would be my shoping list:

That's really helpful - thanks! I'm considering the RFM69 for production build, but I figure the easier to get working (and no antenna needed option) of the NRF24L01 is easiest right now.
Can't beat that price!

@gohan said in Sensebender Europe resellers ?:
Of course, but since price was one of the requirements I just added the cheapest solution 😀
Absolutely fair - I should have said that I'm keen to run the whole thing within my own network. I'd prefer not to use cloud services where I don't need to.
