INA219 on Wemos D1 Mini

[kajmaj]

Hi, I am trying to configure Wemos and INA219 work together, but no success yet :( Wemos is on 6.1 with #define USE_INA219 allowed while compilling GPIO5 > SCL and GPIO6 >SDA

Please post result of command: gpio
(without a 's')

[kajmaj]

15:09:04 CMD: gpio
15:09:04 MQT: stat/wemos_1/RESULT = {"GPIO0":"0 (None)","GPIO1":"0 (None)","GPIO2":"6 (I2C SDA)","GPIO3":"0 (None)","GPIO4":"10 (Switch2)","GPIO5":"9 (Switch1)","GPIO12":"0 (None)","GPIO13":"0 (None)","GPIO14":"5 (I2C SCL)","GPIO15":"0 (None)","GPIO16":"0 (None)"}

[Jason2866]

You have on Gpio14 SCL and on Gpio2 SDA Not the config you wrote. Use web frontend for configuration it is easy.

[arendst]

Try command I2Cscan and see if finds the address of the INA219

[kajmaj]

Hm, changed back as described,

15:23:22 CMD: gpio
15:23:22 MQT: stat/wemos_1/RESULT = {"GPIO0":"0 (None)","GPIO1":"0 (None)","GPIO2":"0 (None)","GPIO3":"0 (None)","GPIO4":"0 (None)","GPIO5":"5 (I2C SCL)","GPIO12":"6 (I2C SDA)","GPIO13":"0 (None)","GPIO14":"0 (None)","GPIO15":"0 (None)","GPIO16":"0 (None)"}

and

15:21:47 CMD: I2Cscan
15:21:47 MQT: stat/wemos_1/RESULT = {"I2CScan":"No devices found"}
```¨
What can be wrong?

[kajmaj]

I will do some soldering and try different I2C for the case that INA219 is faulty

[Jason2866]

Now you have on Gpio12 SDA For example take a look here https://github.com/arendst/Sonoff-Tasmota/wiki/Wemos-D1-Mini-and-TSL2561-Luminosity-Sensor The Ina219 can be connect the same way as the TSL2561

[kajmaj]

Jason, there was my typo error (sorry), wemos has no GPIO 6 available in configuration I´ve tried several combinations and :( Itś a bit confusing, as there are "GPIOs" and "Ds"

[Jason2866]

Ok. You have connected Gpio 5 SCL and Gpio 12 SDA?

[kajmaj]

Yes.

[Jason2866]

Direct connected or via breadboard? Breadboard do often make problems if used for devices with I2C bus... Try to use wires. Soldered or Dupont cables on pin headers

[kajmaj]

Connected directly i.e. INA to Wemos (pin to pin - dupont cables)

[Jason2866]

Maybe the pullups resistors are too high (SCL SDA). If 10k installed change to 4k7 https://learn.sparkfun.com/tutorials/i2c

[ascillato2]

Hi,

Have you manage to solve your issue?

[kajmaj]

Hello, not solved yet.

[kajmaj]

I was convinced that sensor is faulty, just for a case I bought a new wemos as well. So connected together iaw https://www.letscontrolit.com/wiki/images/a/a4/INA219_S.jpg SDA to D4/GPIO2 and SCL to D5/GPIO14. Nothing else is connected to wemos except powerplug. I2CScan - no device found. Tested 2 INAs and 2 Wemos D1. Almost sure, that it is not hardware issue, it must be (moreless) "operators" fault. I am not able to find this fault, Mr. Google is not helpful this time at all. 10k pull ups did not work, must buy 4k7 to try last possibility. Well, measured cirquit is not connected but it should not influence it. Update: 4k7 pull up (connected between Ucc and SCL Ucc and SDA pins do not work as well.

[arendst]

Did you connect Gnd and Vcc of Ina219 to Gnd and 3V3 of Wemos too?

[kajmaj]

I have connected Ucc (3,3V) Wemos to INA, GND to GND, Wemos is powered through micro USB, power plug gives 1A. The only unplugged pins on INA are V in+ and V in-

[arendst]

Strange. Did you enable the INA219 in the source? What firmware version do you run? Pls provide output of command status 0.

[arendst]

Just checked your initial status 0 output and it looks fine regarding INA219 enablement....

I really do not know what else I could do to have it working.

[ascillato]

Hi,

Have you managed to solve your issue?

[kajmaj]

Hi, I wish I did. I've tested 2 WeMos D1 R2 UNO, 1 Wemos D1 Mini, 2 INA 219, various pins combinations but no success. Waiting for one more version of Wemos, I will test it and close the issue afterwards.

[ascillato2]

May your sensor is faulty. Do you have another?

[kajmaj]

As I said, I have 2 INAs, different seller, the same result. If I connect other I2C, it works as expected.

[ascillato]

Hi, any news on this?

[kajmaj]

Apparently, at least in my case, none of Wemos (tested 4) do not work with INA219 and further experiments are wasting of time.

[fast-potat0]

There is little info about INA219 and tasmota and this thread pops up quite high on google, so I'll comment here :)

I have managed to make INA219 work. I have NodeMCU v3. I tried make it work on tasmota.bin. There is no i2c driver 14 that is required there. Documentation about that: https://tasmota.github.io/docs/I2CDEVICES/ You can check what drivers you have available by entering command i2cdriver. There is only driver 7 in this build.

I flashed tasmota-sensors.bin and run command

11:44:16.160 CMD: i2cdriver 11:44:16.168 MQT: stat/tasmota_DAFCE1/RESULT = {"I2CDriver":"7,8,9,10,11,12,13,14,15,17,18,20,24,29,31,36,41,42,44,46,48"}

much better. Driver is here. Configure module to have i2c SDA on D2 and i2c SCL on D1

11:46:16.020 CMD: gpio 11:46:16.029 MQT: stat/tasmota_DAFCE1/RESULT = {"GPIO0":{"224":"Relay1"},"GPIO1":{"0":"None"},"GPIO2":{"0":"None"},"GPIO3":{"0":"None"},"GPIO4":{"640":"I2C SDA"},"GPIO5":{"608":"I2C SCL"},"GPIO12":{"0":"None"},"GPIO13":{"0":"None"},"GPIO14":{"225":"Relay2"},"GPIO15":{"0":"None"},"GPIO16":{"0":"None"},"GPIO17":{"0":"None"}}

INA219 should be automatically found and you should see voltage current and power on main screen.

There is a low change to get a answer in a closed issue. For questions there is Tasmota Discussions. Please ask there
