I'm using analog inputs on my Arduino running the StandardFirmataPlus example sketch to measure pressure sensors. I've modified the sketch to read the analog inputs only every 5 seconds to reduce USB serial traffic and cpu load on both devices but node-arduino does not create a msg and trigger my flow unless the new value is different than the previous one. I want to have a that value saved to a time series db regardless of whether the value has changed.
The two options I prefer are:
Modify the node and remove the comparison.
I don't know how to do that yet.
Request a feature for node-red-node-arduino to pass msgs even if the value has not changed
(maybe also request support for setting the analog sampling rate from within the node, contrib-gpio supports this but doesn't support INPUT_PULLUP)
This could take longer so I like the first option for the interim.
Any other reasonable options?
