2x BME 280 on 2x arduino nano hangs in HomeAssistant

[HJ_SK]

Just restarting to use my arduino's with MySensors (+ NodeManager) .....

I'm using NodeManager for this :

I added a BME280 on a Arduino Nano with
// General settings
#define SKETCH_NAME "BME280_Test"
#define SKETCH_VERSION "1.0"
//#define MY_DEBUG
#define MY_NODE_ID 98
// NRF24 radio settings
#define MY_RADIO_NRF24

• Add your sensors
  // BME_Specific
  #include <Adafruit_BME280.h>
  // End BME_Specific
  It was picked up by homeassistant perfectly

Then I added second BME280 on another Nano
// General settings
#define SKETCH_NAME "BME280_Hof67"
#define SKETCH_VERSION "1.0"
//#define MY_DEBUG
#define MY_NODE_ID 67
// NRF24 radio settings
#define MY_RADIO_NRF24

It first hangs but after hours HomeAssistant did pick it up, but ......
Both are now 'dead' (Not refereshing data) but still visiable in HomeAssistant.

Any one an idea what is going wrong here?
Help much preciated!

Thx in advantage!

Hello @HJ_SK

Could you please post the whole sketch in code tags or as an attachement?
Does it work stable with just one sensor node?
Could you #define MY_DEBUG, attach at least one sensor to a PC and post the log after they hang?

Regards, Edi

thx Eiten,
Thx so much for your reaction.
With 1 BME 280 it is stable within HomeAssistant.
My_Debug later today is the plan

Below ino file

After activate MY-DEBUG I got this error :
Sketch too big; see https://support.arduino.cc/hc/en-us/articles/360013825179 for tips on reducing it.
text section exceeds available space in board

Compilation error: text section exceeds available space in board

I understand because of using NodeManager the file is bigger.
Can I remove all // xxxsensors?

without debug is now hangs on here :

But last time upload after several hours it suddenly came up in HA

[HJ_SK]

And now again on USB port of PC sending its info, but no response in HA

Well, I can only imagine that they try to send at the same time. Did you try with slightly different interval times?

@HJ_SK said in 2x BME 280 on 2x arduino nano hangs in HomeAssistant:

BME280

I had a similar situation. First you have to delete all the MySensors devices in HA. This is aggravated by HA wanting the devices to be on line before you delete them. You may have to delete the MySensors data in the HA config directory. You may even have to uninstall MySensors from HA. Then shutdown HA. Next, turn off your gateway. Are you using MQTT for messaging? You'll have delete the MySensors data from there, too. (MQTT Explorer is good for doing this)

Then start HA. Did your MySensors devices come back as zombies? That's the problem. Try deleting them again. Are they data still in MQTT?

OK, now start again.

I had documented how to do all this deleting in HA Forum, HA/Discord and here, but I can't find that documentation now. grrrr
