Lidl Parkside robotmaaier bedienen met PHP of Domoticz

26 april 2024 Joost

In dit artikel leggen we uit hoe je de Parkside PMRDA 20-Li A1 Robotmaaier kunt bedienen middels een PHP-script.

Uitgangpunten:

Je heb de Tuya Smart app (Playstore of App store) geinstalleerd, een Tuya account aangemaakt en de robotmaaier gekoppeld aan de app. Test even of je de robotmaaier met de app kunt bedienen!
Je hebt een webserver met PHP (liefst versie 8.0 of hoger) draaien.

Het stappenplan bestaat uit verschillende stappen:

Tuya Cloud Project aanmaken
Tuya Smart app koppelen aan het cloud project
PHP-scripts om informatie op te halen of de robotmaaier te bedienen
Tuya API-service verlengen

Tuya Cloud Project aanmaken

Ga naar de developer site van Tuya en maak een account aan.

Log nu in met het account dat je zojuist gemaakt hebt:

Je krijgt nu een vraag over het account type. Klik op Skip this step. You can continue the setting in User Center later:

Klik nu aan de linkerkant op Cloud en vervolgens aan de rechterkant op Create Cloud Project:

Verzin zelf een Project Name. Bij Industry en Development Method moet je voor Smart Home kiezen. Het Data Center moet overeenkomen met het account dat je in de Tuya Smart app hebt. Bij mij was dat Central Europe Data Center. Klik tot slot op Create:

Zorg dat in het volgende scherm IoT Core en Smart Home Scene Linkage geselecteerd zijn. Klik op Authorize:

Je project is nu aangemaakt. De belangrijkste gegevens zijn Access ID/Client ID en Acces Secret/Client Secret. Noteer deze gegevens goed, later heb je ze nodig!

Tuya Smart app koppelen aan het cloud project

Het Tuya cloud project is nu aangemaakt. We gaan nu het account van de Tuya Smart app koppelen aan het cloud project.

Klik nu op Devices, daarna op Link Tuya App Account en tot slot op Add App Account:

Je krijgt nu een QR-code te zien. Scan de code met de Tuya Smart app op je telefoon (rechtsonder Profiel en daarna rechtsboven op scan-icoontje):

Nadat je met de telefoon gescand en bevestigd hebt zie je onderstaand scherm. Kies voor Automatic Link en klik op OK:

Je krijgt de melding dat 1 device vanuit de app gelinkt wordt met het aangemaakte proces. Dat is precies wat we willen 🙂

Als alles goed gegaan is zie je nu jouw device. Noteer het Device ID, dit ID hebben we later nodig!

Klik nu op Robot lawn mower:

Kies hier voor DP Instruction en klik op Save Configuration:

Je krijgt nog de vraag of je zeker bent. Klik op OK:

Nu zijn alle voorbereidingen getroffen om data uit de robotmaaier te lezen én de robotmaaier te kunnen aansturen vanuit een PHP-script!

PHP-scripts om informatie op te halen of de robotmaaier te bedienen

Onderstaand een PHP-script waarmee je informatie uit de robotmaaier kunt lezen. Zelf vind ik vooral de laatste 7 regels van de output interessant:

Hieronder vind je een PHP-script, waarmee je de robotmaaier kunt laten beginnen met maaien. Op regel 3,4 en 8 vul je de waarden in die je eerder in het cloud project bent tegengekomen. De waarde “StartMowing” op regel 9 zorgt ervoor dat de robot begint maaien. Als je “StartMowing” vervangt door “PauseWork” dan zal de robot pauzeren. Op regel 14 t/m 19 vind je alle mogelijkheden. Merk hierbij op dat als je het maaien wil afbreken de juiste volgorde StartMowing -> PauseWork -> CancelWork -> StartReturnStation is. Je kunt dus niet van StartMowing direct naar StartReturnStation
