That issue is caused by the newer ESP8266 core changing yield functions. Downgrading the ESP8266 core to v2.6.2 (or v2.7.4 depending on your board setup) remains the most reliable workaround until those MySensors core PRs get merged into a main release. Keep an eye on those GitHub PRs for updates on full compatibility with current core releases!

Hi all, After 2 years I restarted working my Home sensors and my MySensors projects. I want to create some PCB and decided to start working with KiCAT. I'm using version 5.1 and was able to import libraries and assign 3d shapes to MySensor components. However, the MySensors 3d shapes look to be wrong. Their size is too big when compared with KiCAT standard components. Has anyone of you gone through this issue? Any workaround? Thanks in advance.

Hi2All! Surprising is here. After about 24hours I refresh HA and suddenly my motion sensor was integrated. There is also second entity > battery : 0 , have to look deeper into that for understanding. Need to change little in the sketch, because don't want every short time 'no movement' so only when there is motion and maybe once a hour indication sensor is alive. Meantime I found 3 other good threats: https://forum.mysensors.org/topic/11200/finally-progress-evidence-based-radio-testing-method-and-capacitors https://forum.mysensors.org/topic/1664/which-are-the-best-nrf24l01-modules/27 https://forum.mysensors.org/topic/9550/build-a-reliable-power-supply-chain Very usefull for me also finally progress because of lacking time in the past. Great jobs are done here! Thanks for this all of you guys or girls!

Hello, After installing the Core Update 2026.7.4 HA did not received any data from all my "MySensors" sensors. I use the serial gateway on a raspberry pi 3. The connection to this seems to work: "2026-08-04 17:45:39.160 INFO (MainThread) [mysensors.transport] Connected to Serial<id=0x7f54ec9a50, open=True>(port='/dev/ttyUSB0', baudrate=38400, bytesize=8, parity='N', stopbits=1, timeout=0, xonxoff=False, rtscts=False, dsrdtr=False)" I get no more messages from mysensors after the startup. I tried a reboot as well as a shut down and a complete power cycle. I tried to repower the sensors as well. But this doesnt work either. Sometimes, about 2 to 3 times per day, i get a message like this: 2026-08-05 22:29:42.054 DEBUG (MainThread) [mysensors.transport] Receiving ��D������D��w���^y 2026-08-05 22:29:42.056 WARNING (MainThread) [mysensors.message] Error decoding message from gateway, bad data received: ��D������D��w���^y 2026-08-05 22:29:42.057 WARNING (MainThread) [mysensors] Not a valid message: not enough values to unpack (expected 5, got 0) I tested the serial gateway on my pc. The sensors appear in the serial console: 8;0;1;0;0;21.59<\n> 8;1;1;0;1;58.98<\n> 8;255;3;0;0;85<\n> 5;0;1;0;0;23.40<\n> 2;0;1;0;0;19.05<\n> 2;1;1;0;1;68.34<\n> 2;255;3;0;0;63<\n> I am running out of ideas. On github i also created a issue. Has someone an idea how can i debug or fix this? As last opportunity i can build a MQTT-Gateway. regards, Sebastian

I am making an open source 3d printer as my minor project for college but i am stuck as my motors are not functioning properly, either they are just vibrating at their place or not working at all. I am using Nema 17 motors with A4998 stepper driver and Aurdino Mega 2560. I googled how to know the correct Tx and Rx terminals, as I thought it was problem, but now my motor is not functioning at all when i run it individually with the Arduino, power supply and stepper driver. Can you please tell me how I should get my motors to run? Also the motors are local and so are most of the components.
