@Thomas: thanks a lot for your feedback! I will try that route as soon as I can get hold of a MAX232 chip.

Hi, I am trying to control an amplifier (Devialet brand, which provides for a serial command interface) from my home automation system (Openhab running on Windows). I want to use a D1 mini that will be connected directly to the amp, and commands will be sent to the D1 mini through MQTT. I believe th...

OK, I think the problem was not really in the serial proxy plugin. More likely, it was a harware issue in my setup. Consequently, I am closing this thread. And starting a different one about my hardware issue...
Sorry if I wasted your time

Update: I verified that the wired HW Serial0 connection between my two D1 Mini's is OK. I did that in the following way: 1) temporaily disable the Serial Proxy plugin in one of the D1 Mini's; 2) check the "Enable serial port" box in Advanced Settings of the same D1 Mini; and 3) enter the c...

I understand that the voltages on my application (Devialet amplifier) will need to checked. However, at this point in time, I am just trying to get the serial communication working between two D1 mini's. Both are running the serial proxy plugin. They are interconnected with crossed lines (TX-->RX an...

Thanks for this explanation. So, I will make sure to uncheck that option on the Advanced page whenever I run the Serial proxy plugin. However, since my Serial proxy setup fails to work even when that option is unchecked, I must be doing something wrong elsewhere. Any suggestions as to where I should...

Unfortunately, I have had no luck yet. I tried connecting the D1 mini to the serial port of the Devialet amp, and nothing happened. There was no evidence that the amp was receiving anything whatsoever. Then, I thought I should try conecting my D1 mini to a device that I have more control on. The obv...

Once again, many thanks for your comments. As I mentioned before, I have not connected my hardware (Devialet amplifier) yet. However, I have now managed to simulate communication events in both directions. For that purpose, I am using the Arduino serial monitor (D1 mini connected to Windows 10 throu...

Thanks for your feedback. I am not sure what you mean by numeric data . I need to communicate with the amp using strings such as "[DEVIALET>POWER=0]". The amp is then supposed to respond with the same kind of strings. My plugin is enabled and I have defined an MQTT controller. Through that...

Another (more interesting) update: Good progress: I finally managed to flash my D1 mini. The trick was simply to check both the Post flash action checkbox (enter wifi info there) and the Pause after flash checkbox. Perhaps the problem was that if you let the system do the automatic post-flash, the d...

Update: I tried flashing another brand new D1 mini on a different computer (Windows 11) and I got exactly the same result: COM port error at post-flash time, and no WIFI SSID showing up after flashing-disconnecting-reconnecting. So, it looks like the problem has to do with my Windows environment and...

@TD-er Apparently you have another device connected to your system which also shows up as a serial port. One easy way to check is to see which one is left in the device manager if you unplug the ESP device. Only one COM port is listed in Device Manager, the one associated with my D1 mini. When I dis...

Thanks a lot: now I am starting to understand how to find particular plugins. When I attempted to flash the relevant binary into a new D1 mini using "ESP Easy Flasher, I stumbled onto another problem. I don't know if you can help with that. I am running the esp tools under Windows 10. In ESP Ea...

Thanks a lot for your response (I was starting to despair)!

I am fairly new to Espeasy. What distribution should I use in order to gain access to the serial proxy plugin?

Many thanks again.

Clues, anyone?

Hello all, I would like to control my Devialet amplifier through my Openhab (OH) home automation system. Thanks to some kind assistance I received from this community, I have already managed to implement OH control of my Mitsubishi heat pump, using a D1 mini that receives MQTT instructions from OH a...

Hello all, Some time ago, using Arduino IDE, I flashed a D1 mini in order to try something that did not really work and that I don't care about any longer. I tried to reflash the same D1 mini using Esp Easy Flasher. I always get the same error regardless of the bin file I am using among the followin...

OK, problem resolved! I was able to reflash my D1 mini with the "normal" image and my analog input is now working fine. Many thanks.

Thanks a lot for the tip!
Can I simply overwrite the VCC version by flashing a different one over it, e.g. "ESP_Easy_mega_20200913_normal_esp8266_4M1M.bin"?
Many thanks again.

Here is a newbie question. I flashed a D1 mini using a ready-made config from the Esp_Easy community (ESP_Easy_mega_20200913_test_ESP8266_4M1M_VCC.bin) . I was then able to successfully implement a few different tasks (monitoring contact inputs, triggering relays). I am currently trying to get acqua...
