@circfruit TIL ... I had no idea that would work. Another thing you could do to publish messages the proper way is to install native meshtasticd and configure the lora radio as "sim" then you have a simulated node that can connect to mqtt and be sure all the encoding and encryption is correct. ... also a nice feature of the 2.6 firmware is that it supports UDP which means that all nodes on a network will magically see each other even without a Lora radio.
