    Cool! Where did you end up ordering it?

    Let me know how it goes and if you have any questions / feedback let me know.

    OSHPark, I've ordered from them before.

    So I got one built over the holidays and except for a radio failure after 2 days everything has been working like a charm. I'm running both my LED lights, an Si7021 sensor and I have an old CPU fan hooked up just for testing. I also wired up a couple of waterproof 1-wire sensors I had in a parts bin.

    Great!
    Always nice to see it working for others. Is the dimming function working well with your combination of driver and LEDs?
    Radio failure can happen, they are awfully sensitive to >3.3V and burn easily, I usually always get 1 module on a lot of ten which is bad and burn instantly. If it's working right now you should be good to go forever now.

    FYI the mounting holes are designed for High quality 1 set of Simple PCB Circuit Board Mounting Bracket For Mounting DIN Rail Mounting 2x Adapter+5x Screws-in Connectors from Home Improvement on Aliexpress.com | Alibaba Group to be suspended on a DIN rail. (but of course you can use them for anything else)

    Adjusting the speed of the fan and dimming of the LEDs works great. For the $1-2 cost of the radios I would expect a few failures.

    I haven't figured out how I'm placing everything but mounting it all on DIN rail definitely makes sense. As you can see everything is a bit of a mess right now. I currently have the LED cooling fans hooked up to a hardware PWM controller but on or off it doesn't seem to affect the temperature around the plants so I may just remove them and let convection cool them.

    Nice, let me now how it goes.
    So far I never had a bad radio module in SMD format (but soldering them is sometimes a little tricky between the battery holder and arduino pin headers)

    Are these from PCBs.io or dirtyPCB?

    PCBs.io, I ordered 4 and they sent 6.
