can't pair with SiliconLab EZSP dongle

Sensor SenseAir S8
Firmware 4.0.2 DIYRuZ_AirSense_Router_CC2591.hex
Firmware build date 18/01/2021 11:23
Firmware version 18/01/2021 11:23
Sensor works without any noticeable problems, but sometimes both LED2 and LED3 start blinking for ~30 seconds. LED1 not blink in this time.
Looks like this happen only when detected CO2 concentration below first margin, ie below 1000 ppm. When detected level is higher LEDs works as expected.
I checked the sources and found only one place where both LEDs going to blink - in zstack-lib/mhz19.c, function uint16 MHZ19_Read(void). Possible, firmware incorrectly detect connected sensor?

No activity here for a while. Hopefully someone is still watching the repo.
I'm hoping to use USB micro, and the AliExpress link on the BOM is dead.

I've found potential matches, and thought to check if anyone know which one would fit.

Aliexpress Link
TYPE-C-17 or TYPE-C-18

Hope someone can help.

Please help me,
I managed to connect only 1 time, but I still did not understand how I did it.
I need to re-bind the sensor for for adding converter in Domoticz.
Which button to press: SW1, SW2?
Or power ON/OFF 5 times?
Thank's.

Is it possible to buy a pre-made board ?
I live in France.
Thanks

Suggest the option to turn off the LEDs for nighttime use in the bedroom.

Датчик BME280. Шлюз SLS. Показания в строке давления "Pressure = 10080000000000000". На прошивке 2.0.0 этой ошибки не было.

I have "freezes" (only temp value) after 4.0.2 "router" flashing:

Can be solved by power off/on for some seconds (but you can see temp "spikes" after these off/on's)
Trying to return to the older version

Linking fails:

Error[e46]: Undefined external "?B" referred in bdb_Reporting ( C:\Texas Instruments\Z-Stack 3.0.2\Projects\zstack\HomeAutomation\AirSense\CC2530DB\

Any ideas what I can do?

Thank you for this useful firmware. I wonder why do one need a separate DS18B20 sensor to return temperature data. AFAIK both Senseair S8 and MH-Z19 return air temperature in UART protocol. You can read it and return in absence of a separate sensor.

Zigbee module E18-MS1PA1-PCB out of production. New E18-MS1PA2-PCB module supported in the future?

You use the text "Carbon dioxide has a very negative effect on the human body and is a carcinogen"
CO2 is NOT carcinogen.
With the symptoms you mixed up with CO
See: https://en.wikipedia.org/wiki/Carbon_dioxide

scaled value for pressure was deleted. but it works properly in the previous version.
pls return scaled value for pressure.
without scaled value (and scale) pressure in sls gateway does not work.
also z2m in case of usage scaled values provide more accuracy values of pressure and after convert pressure to mmhg last sign is not lost.
