Not helping you but for your information: https://github.com/Xyphyn/photon/discussions/142
Thanks ! Do you use it with alarmo ? How is the battery life time ? Do you succeed to get battery information via zigbee2mqtt ?
Maybe you can check how versatile made it: https://github.com/jmcollin78/versatile_thermostat Works like a charme here
For people who run a Lemmy instance, maybe an automatic way to deploy photon instead of lemmy-ui ? (Like an ansible role)
Would love that !
