I’m glad to hear of your success Odie, the adafruit-pitft-helper2.sh script to get the display working is a good point to mention if others are watching this, it allows you to select any of the supported Adafruit displays (in my case the 2.8" capacitive one). Which could conceivably be used to take the HestiaPi image and change it over to another similar display skipping the route I took to manually get all the files into a base Raspbian install. How do you do that if the display doesn’t work? the Image has SSH turned on I believe.
In January Adafruit went through a fleury of back and forth, with an update to the script at that exact same link:
Recent (Jan 2018) changes that an “apt-get upgrade” makes break the display’s frame buffer copy, in short if you’re using Raspbian Stretch, that script is the cat’s meow unlike the instructions currently on Adafruit’s site.
I’m far from ready for posting the write up but if you get stuck it looks like you’re about as far as I am:
-I performed the manual Hestia installation, skipping steps profusely the posted instructions are rough but doable filling in the holes. What concerns me about such a process is that my efforts to get off the ground now diverge from HestiaPi proper
-I have temperature/humidity measurement working
-I have MQTT setup to feed my main Openhab server
-I have the PiTFT display working but HDMI no longer works (ah well, I have RDP, I wonder if the resolution is set to match the PiTFT and my TV can’t display it)
-i was intending to implement an additional BME280/SHT31 for redundancy, the framework is already done with how the BME280 is already used I just need to call the script with a different address for the other BME280, or use a different script for the SHT31
-I was going to use the old thermostat for an Emergency-Stop
-I wanted statistics for on/of and long term temperature, I couldn’t find them in the settings files yet (or was intention via MQTT, maybe you’ll cross paths with them as you started with the full image)
-You’re clearly farther along in the enclosure front!
Your need for Things/Items/Rules align with my effort as well, water boiler I think you can ignore, and the heat call would go to the furnace. I have a 7x relay board intending for separate control of heat, fan, AC, HRV, humidifier ie I need 4 outputs. Maybe the things/rules work already for what you need if you ignore the hot water as I think one is to regulate the boiler temperature and the other is to control a water valve to a heat zone?
