Hello, I am new here, so apologies if this isn’t the right category for my question. I am looking to build a sort of wall display/physical dashboard for Home Assistant that will primarily act as a thermostat but to be able to switch to a dashboard for interfacing with HA. So the rough plan was to …

Look here maybe. [image] Raspberry Pi Remote GPIO Instructions on how to integrate the GPIO capability of a remote Raspberry Pi into Home Assistant. But if it was me I would be looking at using an esp based LVGL display,

Agree This one has all the parts you need and is probably cheaper than one of your parts. https://www.aliexpress.com/item/1005008476664408.html

Hmmm, It doesn’t inspire confidence that it’s listed as a legacy integration and it looks like not many people are using it. I was considering an esp based solution but I am worried about responsiveness, and then I would also need to code the whole interface and I couldn’t just use HA’s interface.

Does the high level design have HA in the middle of HVAC mode or Heat call settings? Will the display always be a Lovelace dashboard? If so, what if HA dies, gets rebooted and/or and upgrade deprecates something important or it doesn’t restart? How is control of the HVAC system maintained? It might…

If it was me I would just build a DIY esphome based thermostat, forget the display bit. Buy a cheap tablet and use that as a dashboard. If fact that is what i do. easy and all just works, my thermostat has now been running faultlessly for 6 years. [image] Climate Component Information…

I live around the 45th parallel north, in a pretty well insulated house. We only see less than -10°C once every ~5 years. We had the heat go out once when it was -15°C outside and inside it was around 11°C so not really in danger of pipes bursting or something like that, but those temperatures are e…

This looks like a nice project, the performance is as expected, not great, not terrible. But this doesn’t implement the thermostat function like I’ve mentioned in my reply above to Paul, just a dashboard. It would be the same if I just built a display with a pi, but the pi based one would probably b…

But you can add a thermostat to the dashboard. Just a generic thermostat and place it on the dashboard. If you do go for the ESP-Home route then you can create the thermostat on the device and it will operate independent from HA. [image] Thermostat Climate Controller Instructions for s…

A raspberry pi will not be any more responsive than an esp device, an Esphome device does not need HA to work and Esphome can even generate its own web page. And esphome devices are really very stable, never need updating allow you have that option if you want it.
