You want to indicate by some wireless method that you have initiated a click on a 'wireless handcontroller', whatever that is - is this something you are making yourself?
The first device you listed was a LoRa pair - you could use those.
Then you talked about ESP8266 - you could use those.
Bluetooth has been mooted - you could use Bluetooth.
But before any solution was offered, you bought a NodeMCU and hoped it would do the job. Excellent.
You could have done the job without any extra hardware, if you own a phone with bluetooth or wifi, but no matter.
The NodeMCU will work fine as a wireless node, but my preference is for WeMos devices: http://wemos.cc and certainly if you are in an industrial setting, something with the ability to use an external antenna, rather than that basic pcb antenna. That NodeMCU unit is low on features and rather pricy - you can get a ESP32 for the same price or less. The D1 Mini Pro has 16MB RAM (vs 512kb), supports 5V, and is half the price of the NodeMCU. Something to think about in the future. My opinion of NodeMCU (the hardware company, not the developers of the NodeMCU firmware) is coloured, though. They make boards that don't fit standard prototyping breadboard - how smart is that? They haven't made me feel much better about their engineering since then.
In a warehouse, you may find WiFi coverage is spotty, in which case the LoRa pair will do the job admirably - we have them transmitting GPS data over 5km, through trees, buildings, etc., while on the move.
Im sure you will love programming the ESP series - I hardly ever touch an Arduino any more. IoT has taken over my life.
But, compare specs - there are a number of makers out there now and ESPs ain't ESPs - they offer a number of features and selling points.
I like 5V for compatibility, external antenna points so I can mount in difficult places, lots of RAM - YMMV but when you can buy high-spec for the price of so-so, it makes sense to get the best bang for the buck.
Try the WeMos, I'm sure you will be happy with the different models they have available, and the peripherals they have developed to make projects easy.
(disclaimer: I have no association with WeMos, other than I've spent a few hundred dollars with him over the last year...).
