Was having problems with my internet connection and wanted to monitor it. So I rewrote this script to use powershell and store the results in a table storage. The script is using the speedtest cli from https://www.speedtest.net/apps/cli {: .prompt-info } #$StorageAccountName = "StorageAcount" #$Key = "Storagekey" #$StorageContext = New-AzStorageContext -StorageAccountName $StorageAccountName -StorageAccountKey $Key #$Table = (Get-AzStorageTable -Context $StorageContext | Where-Object {$_.name -eq "Speedtest"}).CloudTable $applocation = "C:\apps\speedtest" $path = "C:\temp\" $SpeedTestResults=@() $SpeedtestObj=@() $i = 0 while ($i -eq 0) { $PartitionKey = "1" $SpeedTestResults = & "$($applocation)\speedtest.exe" --progress=no --format=json $SpeedtestResults = $SpeedTestResults | ConvertFrom-Json $SpeedtestObj += [PSCustomObject] @{ Time = Get-Date -Format "dd/MM/yyyy HH:mm K" downloadspeed = [math]::Round($SpeedtestResults.download.bandwidth / 1000000 * 8, 2) uploadspeed = [math]::Round($SpeedtestResults.upload.bandwidth / 1000000 * 8, 2) packetloss = ($($SpeedtestResults.packetLoss).ToString("P")) isp = $SpeedtestResults.isp ExternalIP = $SpeedtestResults.interface.externalIp InternalIP = $SpeedtestResults.interface.internalIp UsedServer = $SpeedtestResults.server.host location = $SpeedTestResults.server.location Jitter = [math]::Round($SpeedtestResults.ping.jitter) Latency = [math]::Round($SpeedtestResults.ping.latency) } # ---- Move to table storage ---- # Add-AzTableRow -table $Table -PartitionKey $PartitionKey -RowKey (Get-Date).Ticks -property $SpeedtestObj Start-Sleep -Seconds 15 } #$SpeedtestObj | Format-Table | Out-String|ForEach-Object {Write-Host $_} $SpeedtestObj | Export-Csv -Path $path\speedtest.csv -NoTypeInformation

This is my hot tub controler with outdoor shower controler. It is based on a ESP32 and a 4 channel relay module. It has a DS18B20 temperature sensor for the hot tub and a DS18B20 for the water in the hot tub. It also has a DS18B20 for the outdoor shower and a DS18B20 for the water in system. esphome: name: pottastyring platform: ESP32 board: nodemcu-32s wifi: ssid: "" password: "" domain: .lan manual_ip: static_ip: 192.168.x.x gateway: 192.168.x.x subnet: 255.255.255.0 dns1: 192.168.x.x # Enable fallback hotspot (captive portal) in case wifi connection fails ap: ssid: "hottub" password: "" captive_portal: web_server: port: 80 # Enable logging logger: # Enable Home Assistant API api: ota: time: - platform: sntp id: timer servers: - 0.pool.ntp.org - 1.pool.ntp.org - 2.pool.ntp.org dallas: - pin: GPIO13 sensor: - platform: dallas address: 0x67011464EA7EFF28 name: "Pottur hiti" id: pottur_hiti - platform: dallas address: 0x8B0314649975FF28 name: "Vatn i pott" id: vatn_i_hiti - platform: dallas address: 0x110000045976f328 name: "Hiti Skapur" id: Hiti_skapur - platform: dallas address: 0xe10314645814ff28 name: "Hiti Uti" id: hiti_uti binary_sensor: - platform: gpio filters: - delayed_on: 100ms id: fylla pin: number: GPIO17 mode: INPUT_PULLUP inverted: True name: "Pottur fylla takki" on_press: if: condition: lambda: 'return id(pottur_hiti).state < 20;' then: - logger.log: "The sensor value is below 20!" - switch.turn_on: relay_1 - delay: 1min - switch.turn_on: relay_4 - delay: 30min - switch.turn_off: relay_1 - delay: 3min - climate.control: id: pottur_climate mode: "HEAT" else: - logger.log: "The sensor value is above 20!" - platform: gpio filters: - delayed_on: 500ms id: sturta pin: number: GPIO21 mode: INPUT_PULLUP inverted: True name: "Sturta takki" on_press: if: condition: lambda: 'return id(pottur_hiti).state > 38;' then: - logger.log: "The sensor value is above 38!" - climate.control: id: pottur_climate mode: "OFF" - delay: 10sec - switch.turn_on: relay_3 - delay: 4min - switch.turn_off: relay_3 else: - logger.log: "The sensor value is below 20!" - switch.turn_on: relay_3 - delay: 4min - switch.turn_off: relay_3 - platform: gpio filters: - delayed_on: 500ms id: nidurfall pin: number: GPIO33 mode: INPUT_PULLUP inverted: True name: "taema takki" on_press: then: - switch.turn_off: relay_4 - climate.control: id: pottur_climate mode: "off" switch: - platform: gpio restore_mode: ALWAYS_OFF name: "Pottur fylla relay" pin: GPIO25 id: relay_1 - platform: gpio restore_mode: ALWAYS_OFF name: "Pottur hita relay" pin: GPIO26 id: relay_2 - platform: gpio restore_mode: ALWAYS_OFF name: "Sturta relay" pin: GPIO27 id: relay_3 - platform: gpio restore_mode: ALWAYS_ON name: "Loka nidurfalli" pin: GPIO18 id: relay_4 climate: - platform: bang_bang id: pottur_climate visual: min_temperature: 38 max_temperature: 42 temperature_step: 1.0 name: "Pottur vatn" sensor: pottur_hiti default_target_temperature_low: 38 °C default_target_temperature_high: 40 °C heat_action: if: condition: lambda: 'return id(pottur_hiti).state > 32;' then: - logger.log: "The sensor is above 32! then full" - switch.turn_on: relay_1 - switch.turn_on: relay_2 else: - logger.log: "The sensor value is below 32!" - switch.turn_on: relay_1 - delay: 1min - switch.turn_on: relay_4 - delay: 30min - switch.turn_on: relay_2 idle_action: - switch.turn_off: relay_2 - switch.turn_off: relay_1 mqtt: broker: 192.168.x.x username: xxx password: xxx
