Octopus regexes seems to be out of date in various templates

[reedy]

I'm using https://github.com/BottlecapDave/HomeAssistant-OctopusEnergy/releases/tag/v17.1.1, and have used it for many versions, but have had HA to recreate the entity IDs to make sure things are up to date.

Lines 248 to 253 in d1b61f8

	**For Energy Rates**
	```yaml
	metric_octopus_import: 're:(sensor.(octopus_energy_|)electricity_[0-9a-z]+_[0-9a-z]+_current_rate)'
	metric_octopus_export: 're:(sensor.(octopus_energy_|)electricity_[0-9a-z]+_[0-9a-z]+_export_current_rate)'
	```

batpred/templates/sigenergy_sigenstor.yaml

Lines 240 to 253 in d1b61f8

	# Energy rates
	# Please set one of these three, if multiple are set then Octopus is used first, second rates_import/rates_export and latest basic metric
	# Set import and export entity to point to the Octopus Energy plugin
	# automatically matches your meter number assuming you have only one
	# Will be ignored if you don't have the sensor
	# Or manually set it to the correct sensor names e.g:
	# sensor.octopus_energy_electricity_xxxxxxxxxx_xxxxxxxxxxxxx_current_rate
	# sensor.octopus_energy_electricity_xxxxxxxxxx_xxxxxxxxxxxxx_export_current_rate
	metric_octopus_import: 're:(sensor.(octopus_energy_|)electricity_[0-9a-z]+_[0-9a-z]+_current_rate)'
	metric_octopus_export: 're:(sensor.(octopus_energy_|)electricity_[0-9a-z]+_[0-9a-z]+_export_current_rate)'
	# Standing charge can be set to a sensor (e.g. Octopus) or manually entered in pounds here (e.g. 0.50 is 50p)
	metric_standing_charge: 're:(sensor.(octopus_energy_|)electricity_[0-9a-z]+_[0-9a-z]+_current_standing_charge)'

But for example, for mine, the regex needs to be something more like:

• sensor.current_standing_charge_electricity_[0-9a-z]+_[0-9]+
• sensor.current_rate_electricity_[0-9a-z]+_[0-9]+
• sensor.current_rate_export_electricity_[0-9a-z]+_[0-9]+

I'm not sure if the last string after the _ may include letters, but obviously regex can be have both for ease... And I guess possibly trying to keep the old variants working too?

I'll have a look thanks
