as been checked (in my capacity) for I don’t know how many times.
CASE: I have a particle photon with a photoresistor connected between two pins, which publishes the value of the resistance placed in front of the “end” light of a washing machine under my own WIFI. The part of Particle works, so much so that with IFTT I can start Pushbullet when the light comes on with the message “the washing machine has run out”.
I therefore created a mqtt sensor on Hassio, with also the states of unavailability (AFAIK)
[code]
sensor:
- platform: mqtt
name: "Lavatrice"
state_topic: "tele/LAVATRICE/status"
icon: mdi:washing-machine
payload_available: "online"
payload_not_available: "offline"
[/code]
and…
nothing, mosquitto refuses -o, better, truncates-the connection with
[Code]
1556805730: New client connected from 192.168.0.15 as WASHING MACHINE (c1, k15, u'MQTT ').
1556805744: Socket error on client WASHING MACHINE, disconnecting.
[/ Code]
and the sensor remains in “unknown”
This is the Photon code. I’m sure I made a trivial mistake (or maybe not, I’m not very well on MQTT) but I don’t see it.
Thank you in advance.

The problem is that the sensor on HASSIO does not even present the “online” and “offline” payloads.
I’m afraid I got something wrong between PHOTON and MQTT, but …
Again, thanks.
(keepalive?)
