For years, I’ve used an el cheapo La Crosse temperature display in our home.
In actuality, it’s two identical displays, getting the same signal from an outside sensor.
They are a bit recalcitrant, and I frequently have to remove all the batteries and then reinsert so they can synchronize.
Well, we had the coldest morning of the season, and yea verily it’s disconnected… again.
I’ve got a Zooz multi sensor outside that provides good temperature (amongst a number of things) so the idea solution would be some sort of display unit I can write a dashboard for.
So, I’m looking for suggestions on something relatively inexpensive, that I can put on a counter or cabinet to display temperatures and stuff driven of course by HA…
The integration you need is openepaperlink from HACS.
I use my devices with the stock firmware which means you need an ESP32 S3 flashed with openepaperlink Bluetooth AP.
If you flash the screens then you should be able to use any (?) ESP32 with ESP-Home proxy firmware.
I’m putting all the bits and pieces together to craft a small(ish) temperature display.
The intention is for the display to provide local (at the device) and outside temps. Outside is easy, I’ve got a Zooz environmental sensor outside doing that and feeding into HA.
The big(ger) challenge is local temp. I could pull temps from the Nest, but I want actual temps at the device. Individual room temp can vary from the Nest display temp.
Before really investigating too much (?), I bought one (two actually) of these:
The first downside, is it uses the same GPIO pins as the display shown above. The second, is there would be significant handwaving to get the temperature sensed into HA. I’m not averse to going through the exercise, but with two roadblocks already, I’m wondering if there is a better solution.
Any ideas of a sensor that could be used in this instance with ready (easy) integration with both the Pi and HA?
