HomeAssistant + Recteq + RT-700 ("The Bull")

Overview

This will quickly describe some of the steps needed to get the recteq configured in the latest versions of HA & (Local)Tuya.

If configured, you will be able to:

• Display Current and Target Temperatures, Probe A & B Temperatures
• Turn Smoker on and off
• Set Target Temperature NEW

Requirements

• HomeAssistant
• Tuya/LocalTuya
  • Steps here are for LocalTuya, but should be similar for normal Tuya users
• Tuya IoT Platform
• Recteq Pellet Smoker
  • This has only been tested with an RT-700.

Steps

1. Install LocalTuya into HA as described in their docs.
2. Configure the Tuya IoT Platform account. Details described in the LocalTuya docs above.

• Local Keys are hard to find, but the easiest way in the Tuya IoT Platform is by going to:
  1. Cloud (left-toolbar) > API Explorer
  2. Navigating the tree to Smart Home Device System > Device Management > Get device details
  3. Pasting the device_id from the previous steps
  4. Reading the JSON Response and looking for "local_key" with the corresponding value.

1. In HA, configure your first device after loading the integration and connecting the Tuya IoT Cloud Account

• My configuration has never allowed me to use the auto-discover and here it helps because I can configure each dps

1. BE CAREFUL doing the following as there is no chance to edit anything in the Device/Entity after it has been added to HA. You will always need to delete and start from scratch.
2. For Power On/Off: Entity Type = switch, ID/DPS = 1
3. For Probe A: Entity Type = sensor, ID/DPS = 105, Device Class = temperature, Unit of Measurement = F
4. For Probe B: Entity Type = sensor, ID/DPS = 106, Device Class = temperature, Unit of Measurement = F
5. For Smoker Temperatures: Entity Type = climate, ID/DPS = 102, Target Temperature = 102, Current Temperature = 103, Precision = 1
6. At this point should be have a working device with 4 entities. Now, if you would like to have a working Lovelace Thermostat card, you will need to customize the entity itself via YAML configuration.

• You may also want to customize the entity IDs as it was not something available during set-up.

Lovelace Thermostat Card Fix

This is required because the LocalTuya configuration for the entity will not take free-text values and none of the DPS parameters from the smoker itself provide the max/min. We are going to hard-code these. I assume you've never configured a customization before below. If you have, you know where to start :)

1. Create a new customize.yaml file in the root of the config folder. I use the Visual Code Studio host add-on so this is very easy from within HA.
2. Include the following in the new customize.yaml file, replacing the climate.smoker_temperature with the appropriate entity ID:

climate.smoker_temperature:
  max_temp: 500
  min_temp: 180

1. Save the file.
2. Open the configuration.yaml file and locate a line that states homeassistant:; if this does not exist, add it on a new line at the bottom.
3. Indent two spaces, and add customize: !include customize.yaml and save the file. The added text should be:

homeassistant:
  customize: !include customize.yaml

1. Restart HA
