Hi, and thanks for the quick response.
I tried the roll back but found that the Lolin S2 Mini was not an option in that version. I tried the Wemos D1 ESP32 and it would compile but the upload failed "Chip is unknown ESP32".
I am going to try and use an external FTDI to avoid issues with USBCDC. If that does not work I will just use the D32 module.
Thanks for the great body of work and support. I cannot even imagine how much work it must be to try and cover all the different chips and modules.
The integration with Home Assistant makes this a breeze!

Thanks for the response. Can you be more specific about how to request the status from the node?
My understanding is the request format is:
request (Child_ID, VariableType);
But if the Home Assistant entity that I want to request the status of is not a MySensors entity it will not have a Child_ID. So how do I format the request statement?

I am trying to use a battery powered node to control a window blind. The sleep function does not cooperate well with a control entity due to the sleep delay interfering with the acknowledgement timing.
I saw in another post that there is no "optimistic" mode available with the MySensor integration.

Does anyone know if it is possible for a node to request the status of home assistant entity that is not defined as part of the MySensor integration?

Thanks, the 600000 was a typo. Should have read 300000.
I finally got time to set up a terminal on my laptop so I could capture the serial monitor output from the node and then processed that with the log parser.
I could see the node repeatedly attempting to find parent, failing, and incrementing the "transport failure counter", waiting 10 seconds, then trying again. There was also a sequence where 4 failed find parent attempts incremented a "consecutive failure counter". And another where it incremented a "failed uplink counter". I also saw the node initiating the 5 minute sleep interval however the pre-sleep message also failed and hence the node never did get to snooze, it just went back to finding parent. After a fair amount of analysis I was not able to determine what was "special" about the instance when it actually connected or why it occurred at roughly 5 times the normal sleep interval.
I reviewed the MyTransport section of the API documentation but could not find any details that helped.
In the end I lost interest as I decided to just reduce the modem bit rate to the point where the radio would connect reliably. I was surprised to see the node connecting with RSSI as low as -106 dB ( at a bit rate of 2400/4800).

And just to add a clarification, do not modify MyConfig.h. Put the define statement into the sketch for your node (somewhere before line: #include <MySensors.h>), and don't forget to modify your gateway code as well.

Working great! Thanks very much!

I would like to try a lower transmission rate on my RFM69 radios. At the moment I only have one gateway and one sensor.
I tried uncommenting line 801 of Myconfig.h and changing it to #define MY_RFM69_MODEM_CONFIGURATION (RFM69_FSK_BR9_6_FD19_2)
I then reloaded the code for the serial gateway to my gateway node and the code to my sensor node as well.
After the change I was unable to get the sensor to connect. I got repeated TSM:FPAR:NO REPLY.
Am I missing a step here? Is there any reason this would not change the bit rate as desired?
As soon as I commented out line 810 and reloaded the code to both nodes connection was restored.

This seems really strange! I have a battery powered project using an Arduino Pro Mini and an RFM69 radio. It operates a servo that opens/closes my Venetian blinds.
I have it set to smartSleep for 5 minutes (sleeptime = 600000) between cycles to reduce battery drain. It works great in my workroom where it is within a few feet of the gateway and RSSI is about -45 but as soon as I take it up to the the living room where the RSSI is around -85 the unit only updates every 25 minutes. Bring it to the workroom again and it immediately reverts to 5 minute cycles.
I thought -85 was still a reasonably good level as I do not require high bit rate transmission. And even so, how can the RSSI affect the sleep time?
The MySensors code is version 2.3.2 and I am using a serial gateway.

I have encountered the same situation trying to use a switch to control some blinds.
Has there been any update on this issue from either Home Assistant or MySensors, or any workaround developed?

I am trying to build a button sensor on a Lolin S2 mini board. I am using the Binary Switch Sleep Sensor example code from the MySensors library.
When I attempt to compile the code I get an error message:

If I disable "USB CDC On Boot" under Tools, the code will compile and upload but then I am unable to use serial monitor to debug as there is no port to connect to.

The exact same code compiles and runs just fine on a Lolin D32.

I am using Arduino IDE 2.0.2 running on Windows 10. Board library is esp32 2.0.5. The radio is an RFM69CW.
I found a reference that suggested adding a Serial.begin() statement to the setup to initiate a serial port after the restart but this did not work.
I also found it odd that I could compile and run a simple program that reported the SPI pin assignments via serial monitor and it worked fine!
Any suggestions appreciated.
