This was found to be due to a loss of precision resulting from Rtgd converting F to C and JavaScript then converting C back to F. This and other issues were fixed by specifying US units in weewx, like this: [RealtimeGaugeData] ... [[Groups]] group_pressure = inHg group_rain = inch group_rainrate = inch_per_hour group_speed = mile_per_hour group_distance = mile group_temperature = degree_F group_percent = percent group_uv = uv_index group_direction = degree_compass And by adding US 'StringFomats', like this: [[StringFormats]] degree_C = %.1f degree_F = %.1f degree_compass = %.0f hPa = %.1f inHg = %.3f inch = %.2f inch_per_hour = %.2f km_per_hour = %.0f km = %.1f knot = %.0f mbar = %.1f meter = %.0f meter_per_second = %.1f mile_per_hour = %.0f mile = %.1f mm = %.1f mm_per_hour = %.1f percent = %.0f uv_index = %.1f watt_per_meter_squared = %.0f Bob -- You received this message because you are subscribed to the Google Groups "weewx-user" group.
