Using Aqara Temperature and Humidity Sensor with Home Assistant

As part of my heat pump preparation I thought it might be a good idea to have some baseline temperature statistics for the house.

I found the Aqara Temperature and Humidity Sensor which looked like a good option. I bought the three pack and then bought another three just a few days later. I now have them in the lounge, hallway, office, bedroom, summerhouse (gym) and loft (that is where my solar batteries and inverter are).

I could connect them straight to Home Assistant via Zigbee. I put Home Assistant in the pairing mode and pressed the button on the top. They were paired in seconds.

They provide the following data

• Temperature

• Humidity

• Pressure

• Battery

I am only interested in temperature and humidity. Below are the two cards that I have made in Home Assistant along with the YAML. I am only interested in humidity in the summerhouse and the loft.

I am using the Mini Graph Card. I am still playing with the gradients. The gradient is from dark blue (cold) to shades of green (comfortable) to dark red (very hot)

I have had one slight issue. The battery percentage was plummeting very quickly. I have opened a case with Aqara. Saying that they have now stabilised. I found this very old thread on Reddit reporting a similar problem. I also saw this in a Mastodon post and that user has reported the same issue, but his have also stabilised

This is the complete Home Assistant dashboard that I created. It has some other room information. I will be remaking this now that we have sections in Home Assistant
