I have purchased and hooked up the DS18B20 probe to my ALR board.
I have been able to get the RECEIVER firmware uploaded using the ESP32 Bootloader Tool AND I have been able to use the UART Assistant App to send my mqtt, and Wifi credentials to the board. At first there was an error with the firmware upload, but once I sorted that out it all seemed to work as described.
The onboard OLED display says that it is connected to my mqtt broker and I am able to see the device in Home Assistant as an attached mqtt device along with all of the potential channels it could be sending data from (ie. Relay, Analog_A1, DS18B20,...), but I do not see any data from the thermometer being displayed on the ALR or sent to HA. Furthermore, I am not able to toggle the relay on the board when I click the on/off buttons in HA. Its clearly connected, but it doesn't seem to be fully connected.
Is the receiver not able to collect its own data from the DS18B20? Does the receiver ALR not provide a functioning relay?
I tried sending the Arduino reciever sketch to the ALR, but was not successful. I thought this would be a great way to program my own mqtt connection, LoRa recieve (based on your work), and include some basic sensor data from the ALR itself.
Any thoughts or insights you have would be greatly appreciated. Thanks!
