Have you verified there are actually MQTT topics with the information?
MQTT Explorer is great for this.
I have a 4.2" waveshare monocrome display; I at the moment just ran a python script to make a clock. I have it on a pi and not an ESP device. The display was a nice extra, the main purpose of the pi is the USB speaker I use for Text to Speech via Kodi on the pi via Home Assistant. I need to print a new case, but not bad for a first attempt.

Thanks for the reply - nice clock and case.
Yep i am using MQTT Explorer - your right it is great. I also have another display next to it, updating on a 2.9 inch screen (these have partial updates).
The pi works well with eink screens and i guess I’m a little more at ease with python than c++ - i did a tutorial on making a Time, News and Headline device using the InkyWhat screen last year ([https://connected-environments.org/making/the/]
Just for the life of me I cant get it working with HA (well it works but NAN on all data).
edit - solved! i had somehow forgotten to integrate the new esp32 to HA! ugh a rookie error…

Thought those interested in the thread might like to see the 4.2 inch version of using eink for HA data. The layout is a little challenging as there is no style sheet so its x/y pixels and the centre align needs tweaking according to the data…
I was going to do a write up so people dont have to go through the hoops i had to to learn it… as ever with things its quite easy once you know how, but knowing how took a few threads, a couple of bricking the node mcu and a few tweaks on the 3D print (which i will put on thingiverse)…

Just updating the 2.9 inch display to include a clock, maximum wind gust and some minor layout changes - now also updated on Thingiverse (https://www.thingiverse.com/thing:4692418)

I have a slightly unique issue. When I loose internet (due to power outages), I have have a generator for backup power but I loose connection to a time server. I noticed that over an 4 hour period my time is off by over 30 mins.
What are some good options here; I’m running my display on a pi and not an ESP.
My Home Assistant instance is on a PC with a real time clock.
So, should I pull the time from a GPS; a docker network time server, …
There is a chrony addon.
For anyone interested, the 4.2 inch case (pictured a few posts up) is now on Thingiverse to print:

Dose anyone managed to user sensors platform: homeassistant with deep_sleep: ?
I want to use my display from battery, but without deep sleep it runs out in one day. With deep sleep, ESP32 dose not receive changes from Home Assistant, because they happened during sleep.
Are only solution would be, to use platform: mqtt_subscribe instead of platform: homeassistant and send each message manually from HA?

- Do those e-paper displays have an WiFi to connect to HASS RPi to get data?
- What about their power usage in such WiFi mode? How often do you have to change the batteries?
Thank you!
No they do not have wifi.
So what’s that?.. Is it an extra WiFi module that you attach to those displays?
It is the esphome configuration for an attached esp8266 or esp32.

Did you check the link in the first post: home assistant prepares bmp images, esp reads them when waking up?

This page have only scheme, but no code.
I didn’t really understand, in which direction I should read this. Looks like “newer” and “older” on the bottom of the page leads to different articles. In them I found about MQTT and writing ESP code from scratch. Nothing about ESPhome and integration platform: homeassistant into it.
I think there are a number of different projects here. @goosst does not use esphome.
If you want to use esphome then there are several other examples in this thread.
For your specific query, post your MQTT message with retain set, and it will still be there when the esp wakes from deep sleep.
EDIT if I wasn’t clear, you can use platform: homeassistant with mqtt (on my reading of the docs)
But how? I never found anything about that anywhere. Everywhere is written to use MQTT instead of api: <key> And if I am using MQTT I will be unable to fetch data from sensors automatically just by using entity_id from Home Assistant.
I totally understand that it can be done manually. I need to create MQTT message for each sensor, and send them each time value is changed. But it it is big hassle, when ESPhome already have homeassistant platform integration.
I just wander if there is a way to retain messages using ESPhome provided Home Assistant integration.
I assume from the docs because this Home Assistant Sensor — ESPHome says
All other options from Sensor
Sensor says
MQTT Options:
- expire_after ( Optional , Time): Manually set the time in which the sensor values should be marked as “expired”/“unknown”. Not providing any value means no expiry.
- All other options from MQTT Component.
I just received a Lyligo T5-4.7 e-paper display module, which should be ideal for us here because it has great characteristics (4.7inch, 960*540, 16 gray level, partial refresh, integrated ESP32) at an amazing price (30$ approx on AliExpress). Now the problem : the only provided demo is based on Arduino IDE and extremely limited - just displaying text and images, not even wifi-enabled. Arduino IDE is a bit of a pain compared to Raspberry Pi or ESPHome devs. Do you know if ESPHome has plans to integrate this soon? Any experience developping displays on Arduino IDE?
