#Mqtt with Two 3D printers attached.
1 messages · Page 1 of 1 (latest)
I'm running HA on a RPI4. I have two printers running Octoprint on two individual RPI3 systems. MQTT recognizes the two printers and assigned 52 entities for the devices.
In the dash board I have two cards showing the displayed entities from each printer. MQTT has named entities as follows. i.e. "octoprint_bed temperature" for printer 1 and "octoprint_bed_temperature_2" for printer.
You need to change their topic names in octoprint mqtt settings man
i have 5 printers added to hass this way
Unfortunately, MQTT puts data from printer 1 into both entities, resulting in both dashboard cards showing randomly alternating data appearing in each of the displayed entities. I have pictures, but I don't know how to upload...in fact, I'm not sure I'm posting correctly now.
change to /octoPrint/printername on each
they have disabled uploading pictures to this server except for a couple channels.. it's frustrating you have to use imgur or something instead
Where do I change the names? In the controlling RPI, MQTT or HA
octoprint settings in octoprint webui -> mqtt tab on left -> topics tab at top
i name my printers different colors like red, blue, yellow, green, silver
then print upgrades in those colors 😛
Thanks very much, I try and find it
you can delete the old topics after you switch over
and all those old entities will disappear
either using mqtt app in hass or mqtt explorer on your pc or something (i prefer the latter)
Are you saying all the entities will disappear?
?
reread what i said..
when you change the name in the settings (like you need to do) you will now get new device and new entities in home assistant
so the old ones need to get deleted... since they point to nothing
I get it...still looking for topics
I'm not using octoprint add-on but rather MQTT alone.
Thanks for the info.
