DIY LED lens

For my battery powered water leak nodes I wanted to add a clear lens to be able to see communication LED status on Arduino Pro Mini while maintaining reasonable water protection. The quick no cost solution was:
1. Drill small hole in node enclosure against LED location
2. Cover it from outside with masking tape
3. Put some amount of hot glue from the inside to cover the hole, wait till glue hardens, remove masking tape. And voila!!

The output of the display could also be sent over serial, but the whole idea is you can walk around with the doctor and improve your results as you go.

We are of like minds, Don't like the cloud based controls (that's another discussion). In my case I have a Bryant/Connex system, heat pump, variable speed fan and 4 zones. There's a lot going on: the 4 zones creates 16 profiles. The fan speed for a profile will depend on the indoor and outdoor temperature. The thermal fluid pump also has to be controlled. A profile will have an optimal air pressure, so there's a sensor there. The controller works just fine not being connected to the cloud. But I want to set the parameters remotely, Bryant/Connex can do this. I also wnat the status of the various actuators and sensors to show up in Home Assistant. The signals sent over the RS422 are proprietary. My plan was to reverse-engineer the signals. After doing this I'll have to experiment to get the right mix of air pressue, fan speed and thermal fluid flow for each profile. I'd like to do the same for my AO Smith heat pump water heater. I'd like to follow your progress. OSD
