How long is battery life with this setup?

What board did you use underneath the mini pro? Are you powering radio directly from batteries?

@FotoFieber , I've built the same sensor, and it works since now 6 months with 2 AA

Nice board, very compact. Do you know how much does it cost?

Hello everyone, Firstly, I apologize for reviving such an old thread, but I find myself in a unique situation and was hoping some of you might be able to help. I hope everyone's doing well. I have a specific inquiry that I couldn't find a recent solution for. Does anyone here know of a tool to generate "fake" Dooya remote (DC90) RF codes for curtains? I've acquired a few motors without controllers and am trying to integrate them with Home Assistant and Bradlink RF remote. Specifically, I'm searching for a way to generate codes for the Up, Down, Stop, and the "Set" button functions to configure curtain limits. Any insights or guidance would be immensely appreciated. Thank you so much in advance!

We are of like minds, Don't like the cloud based controls (that's another discussion). In my case I have a Bryant/Connex system, heat pump, variable speed fan and 4 zones. There's a lot going on: the 4 zones creates 16 profiles. The fan speed for a profile will depend on the indoor and outdoor temperature. The thermal fluid pump also has to be controlled. A profile will have an optimal air pressure, so there's a sensor there. The controller works just fine not being connected to the cloud. But I want to set the parameters remotely, Bryant/Connex can do this. I also wnat the status of the various actuators and sensors to show up in Home Assistant. The signals sent over the RS422 are proprietary. My plan was to reverse-engineer the signals. After doing this I'll have to experiment to get the right mix of air pressue, fan speed and thermal fluid flow for each profile. I'd like to do the same for my AO Smith heat pump water heater. I'd like to follow your progress. OSD
