Share sensors across Tailscale network

Configuration
1

Hi All,

My scenario is 2 separate Home Assistant servers on totally separate private networks, but they are both joined to the same tailscale network. I can ping bidirectionally between the Primary HA & Secondary HA over the Tailscale network:

  1. Primary HA - Synology Home Assistant Docker Container (so no add-on store)
  2. Secondary HA - Raspberry Pi 4 running HASS

Anyone have a working configuration where you shared a sensor from Primary HA to Secondary HA using the Tailscale mesh?

I’ve attempted MQTT by running a mosquito broker on Primary, but it just isnt working. I’m thinking there has to be a more direct way, since both are technically on the same network (from VPN perspective)…

hi there! found any solution? trying to do the same thing. i want to write the values of some sensors to the MQTT broker of a different HA instance. doing it using Node-red, which can use multiple MQTT brokers. everything is connected via Tailscale. MQTT Explorer sees both brokers, but Node-red is stuck in ‘connecting’ status.
