I have just one but could assemble a second one.
I use a 3400rf kit from greetech.
I also have an RXB6 receiver and a superheterodyne transmitter on the way.

how are they connceted a bread board, or a closed enclosure, or?
Everything is soldered to the wemos board. And it’s in a small plastic enclosure, powered by usb. Contact me per PM if you need more information, we already polluted this topic enough ^^

Does anyone know if there is any ‘ready to go’ / plug and play 433mhz system / dongle? All I want is a simple way to toggle an automation using an RF remote (It’s for use in a car to turn on a gate warning light - wifi / zigbee doesn’t reach).
Sonoff Rf Bridge
Take a look at this post:
Especially the transmitter/receive that @RobDYI explained.
After trying a ton of other things I found this post and it’s been working for 2 years without problems.
By ready to go, do you mean hardware and firmware?
What people do most of the time is to change the RF bridge firmware to have direct control into HASS.
The other possibility is a broadlink RM pro but I’m not aware about the HASS RF integration capabilities. Maybe someone else can answer.
