Remotsy Flashing?

ESPHome
1

Hi

I have some Remotsy devices (www.remotsy.com) that I’d like to reflash with ESPhome. Unhappy I’m unable to reflash them :frowning:
As there is not much documentation avalaible about reflashing and video posted by author is not really helpful, I have tried few things.
First I have soldered as indicated the jumper on the ESP to get it in flash mode: https://github.com/jorgecis/Remotsy/blob/3b1626ec4319c7ce3ea8a4701d4556db1dd7293e/images/remotsy_flash.png
I power the esp using the usb port on board and I have wired my serial/usb adapter on pins on the board.
I have flipped TX/RX on serial adapter but not more lucky ! I have tried also to get reset button pushed while applying power on board but no communication too :frowning:

Any ideas what I’m missing or made wrong ?

Thanks

Vincèn

A bit curious why you bought this instead of a Broadlink that is more or less the same price but can fire in all directions?

Then there is a tuya or similar version.
I just wonder what the benefit of this is as a genuine question.

Well when I bought them few years ago now they looked interesting (getting both receiver and transmitter LED on same board in a tiny format :wink: Now for sure it’s as easy or even easier to use one of the numerous devices avalaible on market but having boards trying to use them :wink:

Side note: how do you do the signature with your HA version ? :slight_smile:

I use a rest sensor in HA that sends the version number and my username to my PHP server.
I then use the same URL in the forum but without the username and the PHP server reads that as “get the image associated with this username”.

The rest sensor is this:

  - platform: version
    name: Installed Version
    image: intel-nuc # change for your system, see https://www.home-assistant.io/integrations/version/
    source: local
    
  - platform: version
    name: Latest Version
    image: raspberrypi4 # change for your system, see https://www.home-assistant.io/integrations/version/
    source: hassio

  - platform: rest
    name: forum_image
    resource_template: >-
                        http://www.hoppvader.nu/hass/version.php?version={{states('sensor.installed_version_2') }}&latest={{states('sensor.latest_version_2') }}&user=Hellis81

Something happened that made my sensors become _2 and I have just not bothered fixing it since I only use it here.

Feel free to use it.

Edit:
One thing though.
When you restart the image will be unavailable because HA is not fully up and running when it updates the image.
I have an automation triggering two minutes after startup that also does a update entity on this sensor.

Thanks for the trick :+1:

Back on topic…
Flashing the ESP on the Remotsy was easy. I soldered some pins to my board to facilitate flashing.

It was easier to connect my UART this way. What may be different is that I powered the board for flashing with 3.3V from the UART.

Oddly, and I have no explanation for it, Rx and Tx were not crossed, (Rx to RX, Tx to Tx).

I am endeavoring to make this work on ESPHome. So far I have code to blink the WS2812 LED, but remote_receive and remote_transmitter are giving me issues. Receive looked like it was working. I can see the code from an IR remote come into the debug, but I am still working with converting that code to something the remote_transmit can use.

Are you interested in trying again?
