I’m looking for an outdoor, water proof (IP65 preferably), battery powered button that can be mounted outside rain or shine.
I’d love to learn if anyone was able to identify quality buttons beyond the lower cost buttons the likes of round button 1 and round button 2
I will take a look to ringbell buttons they should be able to ssupport humidity and rain. Example below :
Nice! thank you @1technophile.
I’m a bit concerned with the lithium-ion battery as they don’t perform over a long life cycle. I can also imagine an overcast/rainy week with limited sun 
I’m planning to use the button to operate a motorized pedestrian gate, it will be placed on the inside of the property for exiting only, I expect the button to be activated at most 2-3 times a day, I imagine a CR2016 battery would perform reliably for 12-18 months.
Given the great range achieved w/433MHz, I’m surprised there isn’t a greater selection of buttons or a professional market for it.
I’m currently trying to integrate into OpenMQTTGateway doorbell buttons without batteries (they use the energy of the button press). I haven’t tested the range yet but as they are not battery powered they are quite interesting.
sounds interesting. please share the design.
