Esphome not receiving homeassistant state values?

[cvo]

I’ve been using a TTGO T5 2.9" v2.2 device with ESPHome, but I can’t get it to display values from HomeAssistant.

Any ideas?

It seems like this should be possible per the alarm example here:

Time & Temperature on OLED Display

Or the various folks using it here:

Using TTGO epaper display with ESPHome

I am something of a newb in the world of Home Assistant, ESPHome and ePaper displays. I thought it might be useful to share my experiences, since my project is now running nicely and doing what I wanted it to do. The display in question is the LILYGO® TTGO T5 V2.2 ESP32 2.9" EPaper. There is information about the exact model at http://www.lilygo.cn/prod_view.aspx?TypeId=50031&Id=1146 which is of some use, but please note that the Pin Reference Description seems to be largely erroneous.

Picture of what it’s doing:

It does run fine and the display reloads, time runs fine too. It’s just not getting a state from any sensors on Home Assistant. Any help would be greatly appreciated! Thank you

[cvo]

Also, here’s the raw values I’m trying to display as shown in Developer Tools:

[cvo]

I think so? (if this is what you mean)

[cvo]

NICE! It lives! – Thank you!!

[iotchris]

Hi, what was the missing point to get the values send to the ESP? I have the same issue (values are not available at the ESP). Looks like I’m missing some tiny last bit.

[Ryan_Grandy (Ryan)]

Any update? I have similar issues. Seems like there is a missing post in here…

[Ryan_Grandy (Ryan)]

I fixed mine, as it was not added in the integration page. I was only working on it in the esphome addon page…

[cvo]

Ahh yes sorry forgot to reply. This is the answer. You can configure ESPHome but still need to add it as an integration.
