    Pressuremon, DIY pressure monitor for kegs

    The pinout in the official schematic is correct. Adc is still work in progress and with the current design you will need a 3.3v sensor. 5v is not tested and would require a new design with voltage divider that would decrease the accuracy further. I would recommend the i2c sensor. Using the...

    Replacement firmware for iSpindel (GravityMon)

    It would be possible if there is a specification on the data format, but i havent seen that

    Replacement firmware for iSpindel (GravityMon)

    Sounds strange, i have not tested the s2 mini in the latest versions, have you calibrated the voltage factor after upgrade? Does the device to into wifi setup mode? I will have a look when I get im back home again

    Replacement firmware for iSpindel (GravityMon)

    I have fixed a few bugs in the v2.2 release, https://github.com/mp-se/gravitymon/releases/tag/v2.2.1

    Well if you are going to power it always then you should be able to power the ADS from 5V but add a level shifter to switch i2c from 5v to 3.3V for the esp so you dont damage the esp. or get a analog pressure sensor that is made for 3.3V, this is the one i tested with (3.3V 0.4-2.4V output)...

    Did you change it on the hardware page or use the "calculator" ?

    Pressuremon, DIY pressure monitor for kegs

    Well, you should not mix 5V and 3.3V design, this might damage the i2c bus pins without a voltage stepper for the i2c. The ESP32 is 3.3V and all the devices should be using the same voltage or you might damage the ESP. If you power the ADC from the 5V that will be always on (as well as the...

    How does you hardware schema and configuration look like ? What is the sensor params ? Can you verify that the voltage from the sensor changes when you apply pressure ?

    Gravitymon v2.2 is now released, available in my webflasher on gravitymon.com and brewflasher. https://github.com/mp-se/gravitymon/releases/tag/v2.2.0 Gravitymon Gateway is also updated to v0.7 which adds support for Pressuremon as well...

    I found an issue with the printout of the temperature so it will be fixed today

    Pressuremon, DIY pressure monitor for kegs

    There are two ways to disable the sleep mode using hardware wiring, either connect the voltage pin to ground or connect the TX/RX pins. Both those should force the device to be always on. If you dont get a valid temperature reading then nothing will be shown, Check the web UI or the hardware...

    Pressuremon, DIY pressure monitor for kegs

    Any esp32 based board should work with the the software, currently the ESP32s2 mini, s3 min, c3 mini and c3 pico will work. Adding support for other boards is easy, its just the pins that needs to be defined. I have integrated the code for the ADS1115 in the dev branch and I'm currently trying...

    Pressuremon, DIY pressure monitor for kegs

    Probably, if there is a mqtt or http api then you can send data to it. I have not tested that though. If you figure it out then let me know and i can add it to the documentation All sensors are optional so you dont need any temp sensor. Adc is enabled but i have some more tests to do to make...

    Pressuremon, DIY pressure monitor for kegs

    Yes, the postage is really expensive. The schematic is quite simple and really easy to create the wiring on a experimental board. I will update the docs with the ADS1115 option as well, it should be powered from the same pin as used for power to the digital sensors and connected to I2C bus #1...
