Request to implement support for ShellyWallDisplay

Great project. However I'm not yet comfortable with adding my own templates.

I just installed a ShellyWallDisplay, with a fully functional MQTT setup. I can see it in MQTT explorer but can't get it to join all the other Shellly devices that I succesfully included in my domoticz thanks to this teacher.

I would love to be able to update the templates so that at least the relay can be controlled through domoticz.

I cant find any API spec to the device "ShellyWallDisplay". https://shelly-api-docs.shelly.cloud/gen2/ComponentsAndServices/Mqtt/

Without information this wont work. Could you push the manufacturer to publish some data, or can you do some MQTT sniffing on your network when controlling the relay?

Sample of MQTT sniffing (using MQTT explorer):

Topic : ShellyWallDisplay-MACADDRESS

online = true

subtopic status:

ble = {} cloud = {"connected": true"} mqtt = {"connected": true} temperature:0 = {"id":0, "tC":23.7, "tF": 74.7} humidity:0 = {"id":0, "rh":39.3} illuminance:0 = {"id":0, "lux":60, "illumination": "twilight"} switch:0 = {"id":0, "output":false, "source":"RPC toggle"} input:0 = {"id":0, "state":false} sys = {"id":"ShellyWallDisplay-MACADDRESS","mac":"MACADDRESS","model":"SAWD-0A1XX10EU1","gen":2,"fw_id":"20240115-105444\/1.2.8-59063a9a","ver":"1.2.8","app":"WallDisplay","auth_en":false,"uptime":63147,"app_uptime":610,"discoverable":false,"cfg_rev":23,"schedule_rev":0,"webhook_rev":0,"platform":"vXD10000M2","available_updates":{},"restart_required":false,"unixtime":1709456460,"relay_in_thermostat":false,"sensor_in_thermostat":false} wifi = {"sta_ip":"xxx.xxx.xxx.xxx","status":"got ip","mac":"MACADDRESS","ssid":"SSID","rssi":-59,"netmask":"xxx.xxx.xxx.xxx","gw":"gatewayaddress","nameserver":"gatewayserver"}

subtopic events:

rpc = {"src":"ShellyWallDisplay-MACADDRESS","dst":"ShellyWallDisplay-MACADDRESS\/events","method":"NotifyStatus","params":{"ts":1709456580,"illuminance:0":{"id":0,"lux":60,"illumination":"twilight"}}}

Switching on or off triggers messages under status and events

status : switch:0 = {"id":0,"output":false,"source":"RPC Toggle"}

events : rpc = {"src":"ShellyWallDisplay-MACADDRESS","dst":"ShellyWallDisplay-MACADDRESS\/events","method":"NotifyStatus","params":{"ts":1709455884,"switch:0":{"id":0,"output":false,"source":"RPC Toggle"}}}

Thank you for debugging, based on your finding i think this has to be a working template for it:

If you can add it to the end of your mqtt_templates_gen2.txt file you can try to teach it.

Almost perfect. You got it right except for the uppercase in the device type: if I change "shellywalldisplay" to "ShellyWallDisplay" in your proposed template, it works like a charm.

Great job, and thank you for your fast answer.

Just for the record (didn't do much of the work), here is the correct template:
