I ve been using the atc1441 firmware for almost 5 months with OpenMQTT - It is super reliable and stable (behind there is a Mosquitto + HomeAssistant + Grafana).
Thanks to this very positive experience i would like to replicate this architecture for more battery powered sensors like BH1750 for LUX Meter and CMJS-811 for eCO2 .
I am looking for a BLE-MCU that can run on CR2032 and that can “beacon” values to the OpenMQTTGateway (mine is running on ESP32).
What are your recommendations ?
Should we try to reuse the Telink TLSR82** MCU and adapt the ATC firmware ? or NRF52 ?
Thank you guys
