As a homeowner in a climate similar to Seattle, I’ve been exploring the possibility of upgrading my two-wire thermostat to a smart version. My current setup uses 48VAC, and I’m curious if this can power a smart thermostat, especially since it only needs to control on/off. I’ve noticed that my XXXX doorbell uses a similar setup to charge its battery, so I’m hopeful a similar solution could work for the thermostat. However, I’m not entirely sure how to proceed with the wiring and power management, so I’d appreciate any insights or experiences others have had with similar setups.
On another note, I’ve been diving into MQTT configurations for my home automation setup. I recently set up a Nodemcu using ESPEASY with an LED connected to GPIO 14. I can manually control the LED via a web command, but I’m struggling to integrate this into Home Assistant (HA) as a switch. From my logs, it seems the Nodemcu is successfully connecting to my MQTT broker (running on my RPI), but I’m unsure how to structure the command and state information to make HA recognize the switch’s on/off status. Any tips or examples of successful MQTT switch configurations would be incredibly helpful!
Lastly, I’ve been experimenting with custom sensors and value templates in MQTT. I’m using an Android app to broadcast data, which includes attributes like android.intent.extra.ALARM_COUNT. However, I’m running into issues where the points in the attribute name are causing the template to misinterpret the data. I’ve tried adjusting the template, but it still doesn’t pull the correct value. If anyone has experience with parsing such attributes or has a workaround, I’d be grateful for the advice.
Overall, I’m excited to continue learning and improving my smart home setup, and I’m hopeful that the community can help me overcome these hurdles!
