Anyone did something with the cheap TM1637Display display? I can find arduino libs but nothing working for linux/node red would love to use it without a arduino if possible thanks!

Any progress on this? Old thread?

I'm currently using python to drive my TM1637-based display. Did you publish your Node RED node?

Actually it is still on my todo list to finish it, I was waiting until had more experience writing in JavaScript before I called it done. It is definitely not forgotten just not the next item. The python solution works well, and after I added a bit of MQTT support, pretty much painless to use with…

Yes. You are right. By now I put together a Python script with MQTT support based on this module . It works nicely and I can switch brightness and display mode via MQTT.

The real trick is driving the i2c (or SPI, whatever your device uses) to get the timing right. In my case, the issue is that NR does not consistently send the data with the correct timing 100% of the time when I drive the IC by NR is as raw a method as possible. This is not a NR issue, if is a mul…
