Was an early user of beestat, and then switched to using a z-wave thermostat with multiple zigbee temperature sensors that were all controlled with a Node-RED flow. I moved houses recently and am back to using ecobee thermostats and using beestat for my analyses!
Lot of very nice changes in the last few years!!
A really useful metric for my old setup was that I used to calculate indoor/outdoor dewpoint and chart it using Grafana. (I actually made use of that data to selectively turn on cooling or a dehumidifier. Worked pretty well, but it would take too long to replicate that setup in the house I’ve moved to.)
But even visualizing indoor/outdoor dewpoint is a useful metric. Therefore I want to second (or third) a request made by others on the beestat community. Can a calculated indoor/outdoor dewpoint be shown in the Thermostat Detail graph?
It would be so useful to know if turning on my air exchanger (or opening windows) would increase or decrease indoor humidity. Comparing relative humidity doesn’t work unless indoor and outdoor temps are the exact same. Indoor dewpoint would also be useful to determine if condensation may be forming on basement walls, which are usually around 55°F.
I imagine the implementation would be trivial, apart from deciding which equation to use to obtain sufficient accuracy throughout the 0-100% relative humidity range.
Yes,
Indoor and outdoor wetbulb temp would be super useful. I was just trying to calc. With psychrometric charts to determine if opening window would help or hurt efficiency this evening. (it’s colder but more humid out side)
